Here lets go down the list.
Bitcore is 58% faster 1070 to 1080ti
x17 is 56% faster
Tribus is 65% faster
Skein itself is 65% faster
Blake14r(Decred) is 69% faster
Equihash is 51% faster
Library is 68% faster
Lyra2v2 is 69% faster
wrong on x17 you can do 70% faster, 20MH with a 1080ti versus 11-12MH
skein is 85% faster, again wrong, 550MH versus 1GH
equihash is more like 60%, 480 versus 780
lbry is 300 versus 500, so less than what you have
i don't know where you pulled those numbers but they are all wrong...i have both card and i tested with the best miner for 1080ti, the alexis 1.0 not ccminer 2.0
