Hi, this would be potentially great, but seems to be incorrect for me (@guttormf). Prior balance for STEEM on 2017-07-23 starts with 121.74 and SBD (a few days earlier) 85.591 which then after a 0.001 transaction becomes 108.559.
My account was established in November 2016, but I didn't use it until July 2017, and I've confirmed on steemd that apart from the 50 STEEM account creation fee I wa s not rewarded before July 2017.
Starting (Prior) balance of VESTS seems to almost correct though. It should be 50 STEEM powered up on 2016-11-10, at which point 1 VEST supposedly converted to 0.0004312564126868444 STEEM according to @jesta.
I suppose I can still rely on the transactions themselves though, just not the calculations.
