I've told you to address the specific issue.... over and over again.
The issue is about the supposed blast zone, around the LM, claimed to be seen in images taken from lunar orbit, but cannot be seen in a single Apollo surface image.
Don't act the fool .... you absolutely know that this was/is the specific issue I've been asking you to address.
No more hiding away now, please...
how can i possibly address the blastzones properly when you have repeatedly shown that you DO NOT RECOGNISE WHAT THE BLASTZONES WILL LOOK LIKE!!!!
the whole purpose of making you understand the dark regolith and the bright regolith of and around the bootprint is to show you what dark loose regolith would look like and what compressed regolith looks like..
so far you have only able to admit what compressed regolith looks like, you have still failed to understand what loose regolith looks like even though i have repeatedly given you the answer you are still too dense and ignorant to admit it.

No s#%, Sherlock!
You claim that the 'blast zone' exists, and it's not a problem that we see nothing of the 'blast zone' in surface images, because I don't understand, nor recognize, what any 'blast zones' look like!!??!
You hold up images of footprints, which are surface images. Why you'd believe it supports your argument is baffling...
If you don't 'recognize' why seeing footprints in surface images would support my entire argument, it is not seeing a 'blast zone', in the same way...
"It is commonly believed that man will fly directly from the earth to the moon, but to do this, we would require a vehicle of such gigantic proportions that it would prove an economic impossibility. It would have to develop sufficient speed to penetrate the atmosphere and overcome the earth's gravity and, having traveled all the way to the moon, it must still have enough fuel to land safely and make the return trip to earth. Furthermore, in order to give the expedition a margin of safety, we would not use one ship alone, but a minimum of three ... each rocket ship would be taller than New York's Empire State Building [almost ¼ mile high] and weigh about ten times the tonnage of the Queen Mary, or some 800,000 tons." Wernher von Braun, the father of the Apollo space program, writing in Conquest of the Moon, 1953.
I confess that in 1901, I said to my brother Orville that man would not fly for fifty years… . Ever since, I have distrusted myself and avoided all predictions.
— Wilbur Wright, in a speech to the Aero Club of France, 5 November 1908.

Even more suspicious is the fact that Werner Von Braun already stated in 1952 that it would be impossible to construct a moon rocket due to its enormous size and weights etc. See quote below:

...Did he get it right or not?.....
The main advantage of LOR is the spacecraft payload saving, due to the fact that the propellant necessary to return from lunar orbit back to Earth need not be carried as dead weight down to the Moon and back into lunar orbit. This has a multiplicative effect, because each pound of "dead weight" propellant used later has to be propelled by more propellant sooner, and also because increased propellant requires increased tankage weight. The resultant weight increase would also require more thrust for landing, which means larger and heavier engines.[6]
Direct ascent was basically the method that had been pictured in science fiction novels and Hollywood movies. A massive rocket the size of a battleship would be fired directly to the moon, land and then blast off for home directly from the lunar surface. The trip would be like that of a chartered bus, moving from point A to point B and back to A again in one brute of a vehicle.
Strong feelings existed within NASA in favor of direct ascent, largely because it meant the development of a proposed giant booster named the Nova. After the engineers made their calculations, however, NASA realized that any single big rocket that had to carry and lift all the fuel necessary for leaving the Earth's gravity, braking against the moon's gravity as well as leaving it, and braking back down into the Earth's gravity again, was clearly not a realistic option-especially if the mission was to be accomplished anywhere close to President Kennedy's timetable. The development of a rocket that mammoth would just take too long, and the expense would be enormous.
In retrospect, we know that LOR enjoyed several advantages over the other two options. It required less fuel, only half the payload, and less brand new technology than the other methods; it did not require the monstrous Nova rocket; and it called for only one launch from Earth whereas EOR required two. Only the small, lightweight lunar module, not the entire spacecraft, would have to land on the moon. This was perhaps LOR's major advantage. Because the lander was to be discarded after use and would not need return to Earth, NASA could tailor the design of the LEM for maneuvering flight in the lunar environment and for a soft lunar landing. In fact, the beauty of LOR was that it meant that NASA could tailor all of the modules of the Apollo spacecraft independently.

It doesnt matter, it is still the same payload that is lifted to the moon and back, there is no way to get around that. When the tank is empty the weight is almost zero of the shell.

Yes its a difference although it all sounds like some kind of imaginary stuff created by film producers and not engineers. Assuming that that wasnt yet another fictional idea yes there is a difference of course if they could realize it.
But it can never be 200 times better than the original calculation. Finger in the air tells me maximum 10 times better, never 200 times better. Probably more like 3-4 times better. I think anyone who has a sense of maths will agree.
If anyone shows me the maths of Von Braun and then the maths of the actual voyage, then we could see if there really is some magic trick we couldn´t imagine. But these calculations never seem to show up so until they do I reserve my judgment. I trust Von Braun 100 times more than NASA especially since he said they created all kinds of hoaxes. The truth is that there was(is) only one global and evil power and it controlled(s) the whole world including Soviet Russia. My two cents.

the bright regolith around the dark soil IS PART OF THE BLAST ZONE, that is why the dark patch stand out so much.. the dark patch of regolith is how dark untouched regolith would be when viewed from that angle.

Again, the problem is that there is no blast zone, no bright regolith, which you claim is around the dark soil, in ANY of the Apollo surface images.
That's why you cannot outline the blast zone, in any of the surface images - because there is absolutely nothing to outline!
