I found the notes I took when talking to our applicator (we were owner-builders on the finish of our pool). As I mentioned previously, it seems that different applicators have a different # of price levels and that some charge by perimeter (linear) foot and others by interior square footage.

Our applicator had 3 levels of pricing, no difference between Tec and Sheen, and charged by perimeter foot.

Standard: $37.50/perimeter foot
Upgrade 1: $42.50/PF
Top-of-the-line: $49.50/PF

I did not write down all the colors in each level, but can tell you that Midnight Blue PT would have been in the "top-of-the-line" pricing.

These prices also appeared to be what the applicator charged the PBs and not resulting prices to pool owners. Company also had various other charges for deeper pools (8'+), more steps, baja shelves, special color combos, etc., etc.
