awesome, is the code open somewhere? just interested in how to get started with coding for steem =)! How about tweaking the answer a bit, maybe something like:

<DD.MM.YYYY HH:MM:SS>: TPOS's current balance is 362.869 STEEM tipped by <X users/number of tippers>, your return tip estimate is <totalamountofsteem/number of tippers>

when calculating the number of tippers you would have to take into account only the transactions since the last payout, let's say since the last saturday at 0:00.
