On the face of it...and although for the most part it's being sensible advice under some circumstances, such experimenting does nothing to validate the "What will it be/look like/perform like when finished...?" part of your situation. And did I not see where you said specifically that you Wife does not want you to paint on various different screens forever...? (2x is forever to a Wife...)
How big of an image you can shoot onto a Primed White wall in a dark room has about zero importance or relevance as to what size screen and shade/composition of Gray will actually serve you best by giving you the performance your hoping for.

Well there ya go......,
Speaking for actual experience with the 8500, I say that while it has a most excellent image "as is" on a ideally made White surface, it looks/performs better on High Contrast surfaces that do not overly attenuate incoming Lumens. Blacks don't wash out, yet Whites are able to look brilliant. But as for certain, Primer ain't all/any of that, and can't measure up to actual well formulated White DIY Screen paints...or light Grays, be they simple or advanced for that matter.
A lot of that is due to one thing the 8500 possesses....lumens. And in truth, a lot of lumens isn't something you shoot on a White surface. Any Gray surface you can use to shoot on that can reduce the need for too much action by the Iris will conserve displayed lumens, allowing for more contrast than would be seen in an image on a adjusted "White" surface
Somewhere between PJ, screen size, and screen color/make up...a balance must be reached to obtain the best possible performance. You can get as close as an approximation as you need by supplying such info that states what you have...and what you want, that will allow you to proceed apace.
And you did that...so here ya go:
You need some gray...and also maintain at least a gain of 1.0 SS w/33% Poly will come in close to 1.0 as long as it is applied over a smooth, White primed wall, or better still, on top of a Semi-Gloss Interior Enamel (Water based) wall surface.
Straight SS without Poly will cover the underlying surface to opaquely to allow it to render any help...especially if rolled.
You can get started and be sure that with the suggestion you take you'll get better performance that any halfway measure will provide. And best of all, you'll be done....not still in the planning stages.
But what will you do...what WILL you do....? That still has to be up to you. If a wall sized SS Screen is your abiding interest and desire, we can go there and getter dun. Just let's DO IT...not waste time. The Decade is almost over!
Want truly Epochal "PoP"?
Go send me a PM and/or start another thread. It ain't hard, expensive, or time consuming to reach another level, but that's a tale for another thread.
