The 96% reflectivity is, I would guess, written all over in Mylar's adverisement... let me check...

Yeap... from www.BGHydro.com, """Mirror-like mylar is one of the best and most affordable reflective materials made, with over 98% reflectivity."""

As to the 86% figure, I don't think he looked it up in a Materials Handbook... but, I think it's a pretty good estimate. I mean, I would be impressed if a painted surface (white) reflects over 90% of light... I think that even 86% is a high figure... So I guess he just threw in a ballpark figure for the math...

Either way, it gets the point across.
