Rebels Push and T-Bone on Full Kelly

The Mississippi Rebels lost their rivalry game yesterday by one point, but unfortunately that was all they were getting, so the game resulted in a Push.

As of right now, we will have five more College selections in Week 14 of the season this weekend, including two today - Miami (Ohio, not Florida) and Kent State who are getting 3 and 4.5 points respectively.

Week 14 is pretty much the final week of the regular College Football season, with just a handful of Week 15 games to come so at 59-37-7 I think I'm safe in recording a nineteenth consecutive winning season for these selections.
On the NFL front, it's looking like a quiet weekend with just a couple of probable Road 'Dog selections, although we do have five Under bets to add a little interest.
 
Triggered by Church of Betting's post on staking referenced in my previous post, I thought I'd show the outcome of using Full Kelly on baseball's T-Bone System this summer. Results have now been updated to include 2019 by the way. 

Note that this isn't every T-Bone selection, but a sub-set comprised of selections where the edge is historically larger.
From 2014 to 2018 (i.e. 5 seasons), the ROI on these selections was 13.1% from 352 selections, and the ROI for 2019 ended up being in line at 13.4%. 
The initial bank size was £1,000 and I used a stop loss at 67%. Fortunately this was never hit although we got close with two losses in the opening four selections, a risk of this extremely aggressive staking system.

Note that when there are more than one selection on a day, the stake on each game is the same and the bank is only updated at the end of a day, not after each bet. Most of us have better things to do with our time, and some games are played simultaneously anyway. 

The final bank was £3,555.31 after peaking at £4,091.26. The stop loss moved to over £1,000 on Star Wars Day, after which we were playing with house money.

  1. If the Kelly utility function (log bankroll) took the stop loss into account it would suggest betting less than Full Kelly. Not sure if that interests you.
