The math is meaningless.

Even Mylar @ AN 'ALLEDGED' 98% relfective rate is uselss if its not properly laid flat against the surfaces. It will have dark spots that eat light.

White plastic is great as well as long as the surface is flat you will get up to 86% reflection.

Personally I prefer white as it causes a 'diffusion' of light as opposed to a direct reflection like you get with Mylar.

Your calculations need to contain footnotes that all mathematical equations are based upon proper setup, install and relative FLAT surfacing of your materials.

Mylar may be 98% reflective, but NOT if improperly hung. Same with white.
