Old Smokey, could you give us a concrete example of how you deal with the reduced V1 (wet) and its consequences on go-accelerate distance? My brain is pretty much going along the same lines as Green Cactus...
The stuff they give you in most JAR Perf books spend very little time talking about how real life T-O tables are put together (mostly because the aim of the books is help you deal with the dreaded CAA graphs...)
Cheers
