Lol. I will exclude the other start times like 7:30 pm to keep it that classic BTN/FS1 dichotomy of being the "early game" or the "late game," and I can only go back a few years ... but here you go!
2023-24
6:00 pm: 1-0 (W at OSU)
8:00 pm: 2-0 (W vs. NU, W vs. MSU, L at NU)
2022-23
6:00 pm: 3-1 (W vs. OSU, W vs. UNL, L at PSU, W vs. Michigan)
8:00 pm: 4-1 (L at NU, W at UNL, W vs. MSU, W vs. Minnesota, W vs. NU)
2021-22
6:00 pm: 5-2 (W at Iowa, W at Minnesota, L at UMD, W vs. MSU, L at RU, W vs. PSU, W vs. Iowa)
8:00 pm: 2-2 (W vs. Michigan, W vs. Wisconsin, L at Purdue, L vs. OSU)
So not sure I really see a trend or whatever, but it is kind of concerning that in the last couple years, we seem to play worse in these big weekend games?
