Has anyone been playing RSIF so far? I took a crack at trying to build a chart, and not sure if it flat out sucks or the variance is wild in RSIF. YTD I have RSIF yes @ 42.75% for the 130 games played so far. This by itself would suggest to me that it's just variance especially considering sample size, but I don't want to be totally naive and chase.
My data used to build a chart included 10,800 games with the historical results below.
Code:
Total count RSIF
6.5 145 44.14%
7 552 48.19%
7.5 1230 48.78%
8 1539 50.49%
8.5 2193 51.48%
9 2197 54.94%
9.5 1321 52.76%
10 611 54.01%
10.5 450 59.78%
11 236 58.90%
11.5 119 58.82%
To me intuitively it didn't make sense that a higher total game has a lower RSIF%. To counter this assumption I regressed the historical RSIF vs the total so that I could create RSIF numbers where the RSIF for my chart at 7.5 is greater than my RSIF number at a total of 7. Is this assumption disastrous, decent, or solid?
An additional assumption I'm making is that we are likely to be favoring the yes on RSIF pretty heavily, very rarely betting no RSIF based on the approach I'm taking. Books I've bet this usually have the no as a fav. Can anyone confirm from experience that I have this correct that yes bets are likely to outweight no bets by a considerable margin?
When using the RSIF numbers generated by the above process, taking any bet with edge > 0.00% based on my RSIF chart, the chart has an ROI of -21.12% n = 80. Filtering for only betting RSIF when edge is >2% , ROI is -20.51% n = 47. Filtering for only betting RSIF when edge is >3% , ROI is -7.11% n = 39 games.......so small sample sizes for my results and seems like RSIF been hitting far less than years past, but just hoping for a sanity check.
