As of the time of this writing, the wheel spin bonus costs 594 RP and the base awards are 32 BTC/Lottery/RP. Assuming you value tickets, RP, and BTC equally (for the sake of simplicity), it takes 18.5 rolls to get the equivalent amount back, if you only ever got the base rewards. However, rolls of base rewards make up 900,000,000/1,000,000,000 possible rolls, meaning you have a 10% chance per roll of getting higher than base rewards - 6% chance of 10x rewards, 3.98% chance of 100x rewards, and 0.02% chance of other rewards.
I think this is a very good analysis.
I don't have a lot of experience with WoF spins and chances per roll. Can anyone confirm this? Are these numbers correct?
by investing 3,600 RP for 5 WOF SPINS/ROLL (at current BTC price), rolling 10 times for 50 rolls and spinning them
on average you would get 15 nominal rewards, 1 10x reward and 1 100x reward in each of 3 categories (SATS, LOTT, RP)
for total of of 4,125 SATS, 4,125 LOTT, 4,125 RP (average at current BTC price).
