I lost sleep last night.

42 Ring: 1,27,11,37,21,5,31,15,41,25,9,35,19,3,29,13,39,23,7,33,17.
52 Ring: 1,7,13,19,25,31,37,43,49,3,9,15,21,27,33,39,45,51,5,11,17,23,29,35,41,47.
Every odd-numbered link is visited in both rings. But A fixed/SS chain is I guess 8-16 links shorter than a derailleur chain, so the question is, how many links do you remove from the chain to maintain this?
..and that, kiddies, (that includes me) is probably why the old 'long' dropouts had an inch's worth of adjustment- so you could refine your fixed/SS chain length by two links, or even four links, to get all your teeth visited, and still get your chain tension right..

That looks to me like 110 links.
