I've just gone and had a look at my vote value in one of the tribes.
A 100% vote from me in that tribe seems to be worth the equivalent of 9.71 steem (less 1% fees for withdrawing from Steem-Engine), compared to the steem/SBD world where a 100% vote from me appears to be worth 0.6 steem, or, at best, 1.31 steem ("true" value) as calculated in steempeak.
