in market times, 8-9 days is a very long time so you should no longer have any doubts about the results of the kind of fund transfer that OP was pointing out. it is now clear that it had absolutely no effects on anything whatsoever.
as for coins in circulation you can calculate them easily by multiplying the number of blocks by their reward (it starts from 50 and halves every 210000 block) and then reduce about 100 of it for truly lost coins like burnt coins and miner mess ups to get the real value of circulating coins. the other type of "lost coins" like people losing their private keys, satoshi's coins,... are not lost and there is no way of measuring them.
