I am looking at it seeing 4 maybe 5 gears used on the big ring (12,13,14,15 + 17) another 5 on the middle ring (14,15,17,19,21) and 4 on the small ring (19,21,23,25). With the compact 10s combo I see the 50 with 11,12,13,14,15,17,19 then the 34 on 15,17,19,21,24,27. There is a bit of a jump there, maybe the big rings works up to 21 then a 21 to 15 jump on the back when down shifting. Maybe this isn't that great a plan...I don't know.
It's not cheap I know so I don't blame you. Heck I got other things I need more than a Campy 10s conversion considering my ultegra 9s works perfectly and isn't even that old to begin with.
I still think it is a good way to get a decent range of gears with only one chainring shift.
