Proj. will have 1700 lumens & my throw is about 11.5 feet.
A gain of one is about that of a piece of computer paper. .95 is not much different,neither is 1.1
With 100" screen and less that 12' projector distance and 1700 lumen you are splitting hairs and the screen will be very bright.
The more important thing is screen texture and hot spotting will either it be visible from you seating distance?
Buy the projector first, order free screen fabric samples from the vendors and test them.
