Steve, water can be used in several ways to achieve a level surface. I've used a plastic tubing rig to provide the water level bulb for putting up walls, a suspended ceiling, and laying down a new floor in my own basement a few years go. It works great on a relatively small enclosed area, but I never actually measured its precision. I only know it was good enough for my basement. I'm not at all so sure about using that method in ancient times when they had no practical air-tight tubing technology, let alone one that could cover a 13 acre perimeter. It's not even clear that the Dynastics knew how to establish the normal vertical or right angle or that they had a means to establish true north. And what did they use to establish a straight line, especially for distances of hundreds of feet? Line of sight can't get that degree of accuracy, especially along those vertical angled corners as they applied the casing, or along the passges (recall Petrie's 1/50" precision along the entire 150' length of the Descending Passage masonry).
Meanwhile, to use a water pool that's exposed to hot desert sun strikes me as entirely too problematic since the levels would continually change as water evaporates off and new water is constantly being added to maintain a prescribed level. It might be possible, but I don't see how that would actually work. Of course a non-evaporative liquid like oil would be a far better method for establishing a true horizontal palne, but oil has its own obvious problems. Meanwhile, in Lehner's paper on the composition of the pyramid's perimeter troughs, and various walls, drains, etc., he made it very clear that using a water pool as a leveling means within which much excavation was performed to level the field across that pool will create a very muddy pool and work surface which would render that method's ability to serve as a leveling pool as essentially nil.
Having said that, a water leveling system seems to be the most viable option available to the known Dynastic toolbox. I'm just not convinced it's a sufficiently practical means to achieve that level of precision and accuracy on such an industrial scale.

I disagree. I laid and built patios for extra money in my early 20's.
Once the Pyramids foundation was leveled and the surface cleaned, from there on you are not pulling a great deal of dirt upward. True I have never chiseled casing stones, though I have chiseled plenty of red brick. It in no way, produced anything significant, to mix and create mud. The chips break of and remain clean.
How much chiseling was done, would depend on how well and pre-cleaned (?) the blocks were, and how close to the finished dimensions was required. They may have
swept sand containing plaster into the low spots, and then added water. That is how I use to do it. I laid the bricks first, tamped them down, and with pieces of wood to measure the space between them accurately, I swept in the concrete/plaster sand mixture. The last step is to add water, and let it dry in the Sun. No doubt, those patios are still in place today.
Additionally, if you poured water and stopped slightly above the highest point, it's just a matter of waiting for the water to calm, and the sun to begin evaporating, exposing the high points. This could be repeated often, until filling in the divots with plaster/sand. You could even dam off sections.
I can't see how any sight mechanism would work efficiently, as you can only point to one area at a time, where as, water would expose hundreds of high spots, all at the same time. A sight mechanize...a little to your left..no not that far, go back a little...whoops... that's a little to far?
That will not cut it.
