Could it be an issue of chain length at max ovality rather than the size of the ring itself? I'd read that 60t would cause problems with the fold but nothing about shifting. The top BWC people seemed to be running 60t without any issues last year...

yup! well yes and no...
At times I have to make a few tweaks, but generally its perfect. Because the chain tension is not ideal I assume that causes it.
On a 54t you use a 102l chain, 58t you would need 104. therefore on 56 or 60 you have to use a slightly longer chain than ideal - being 103 or 105 and this means there isnt as much tension in the system. Whether that actually makes a difference, I could not say for certain, but id say 1 in 100 shifts has a little slowness to it

@umop3pisdn
~60t chainring users (@maynardeames ?), do you have any shifting issues on a two speed?
Changed to a 58t (59t peak) oval ring and trying to work out if it's causing a shifting issue where the top pulley on the chain tensioner slips out of the shifting unit.
