colorado move from +21 to +18

[MalikHusam]

should I bet this all the way to +17 orso? does +17 or +21 make my difference %wise?

because I think game tied at half and 7-10 pts late in 4th either way!

wk 2 418 Colorado from -41 to -45, win 56-7
wk2 314 Michigan from -34 to -37, win 51-14 (or push)

based on that itsa 8% chance to land 17-21
so taking -102 with +17.5 is preferable to -130 with +20 because 92% of the time it doesn't matter but you win 27% more if they cover
