Fun with numbers

If you know me, you also know I enjoy playing with numbers and trends around weight loss and other things.
I’ve been recording my weigh-in results in a spreadsheet on my phone for about 2.5 years. About three months ago I started recording my daily WW points consumed and my calories consumed on each day as well.
So I took that stuff and tested the relationship between my weight and my points and calories consumed. It’s a test known as R-squared, and if two sets of data are perfectly correlated - in other words, a change in calories drives a similar change in weight - it produces a value of 1. If they are inversely correlated - when calories go do, weight goes up, for example - it produces a value of -1.
0.167 comparing WW points to weight
0.019 comparing calories from MFP to weight
0.00018 comparing net calories (consumed minus burned) to weight
0.141 comparing average daily calories by week to official WW weekly studio weight.
Short version is there’s minimal suggestion of any correlation between when I eat and what I I weigh on a daily basis. I’d be curious to know if that absence of correlation is a function of being at goal - in other words, there’s no trend to it. I’m not curious enough to go back and recreate some history from when I was losing, but maybe some snowy day when there’s nothing to do . . . .
Any thoughts, comments, suggestions or observations?

TOL and I have found that I'm more apt to have the gain in 2 days, her in 1.0
