OK, so I did the last 5 years, but ignored last year because we didn't play at XL.
O. M. G. The effect expected by this board is real, and it's huge (at least over the 4 seasons analyzed)!
| Gampel FG delta | Gampel 3P delta |
2021-2022 | .100 | .057 |
2019-2020 | -.005 | .000 |
2018-2019 | .060 | .087 |
2017-2018 | .067 | .153 |
Mean | .056 | .074 |
Over the aforementioned seasons, UConn's average FG% advantage at Gampel was 5.6% better than at XL. Their relative 3P% advantage was 7.4 percent better! I am completely shocked at how stark this difference is. Granted, this doesn't say anything necessarily about wins and losses, but damn!
I am not an expert in statistics, so please feel free to critique my method. The link below will bring you to the spreadsheet I created and used for the analysis. Let me know if you have any questions regarding the methodology.
