Your math isn't simple, it's spurious.
And what's so surprising about heads coming up 6 out of 7 flips? That's completely normal.
The fact that you consider 6 out of 7 flips totally normal sounds like you don't get statistics.
6 out 7 heads is about a 6% chance.
You really think that's what's been happening for the past 7 years?
A 6% statistical fluke?
If you have a more accurate way of showing it mathematically, put it out there.
But it's clear we're losing because our team is not as good as theirs.
We break worse and we handle pressure worse.
There's plenty of tangible stuff you can track:
Count how many times we don't make a ball on the break or scratch on the break.
Count how many times we make a huge error that is unquestionably "dogging it"
(like earl trying to thin a 1 ball just now and whiffing, giving up BIH and costing the rack).
Count how many times players hook themselves playing shape, or miss a routine shot.
Any way you wanna add it up, this is not bad luck. We're getting outplayed year after year.
