Thanks for the good word Z! Right now I'm backed up and the wait is longer than usual, due to an illness in the family, but working on it.
"When you order an endless loop string you are measuring from the whole string including the loops correct?"
Usually, but it could vary I guess, depending on who made it.
"I measured my string from loop end to loop end, are strings measured differently than that?"
AMO/ATA states they should be measured under tension, but they are measured loop end to loop end.
"How do they measure strings? Is this my fault or their fault?"
My guess is it's theirs.
"Also, my BW PCH is 53# at my draw lenght 29", what is the SAFE number of Fast Flight strands to use on this bow with an ENDLESS LOOP string?"
If you mean the Fast Flight brand, I'm not sure. If you mean "Fast Flight" type materials in general, it depends on the type material and who you ask.
"Is it different for FLEMISH TWIST?"
No--same strand count for either one. Flemish is a bit more adjustable, but not enough to make up for being a couple of inches off.
