Can you predict PEM by tracking your crash patterns?

so i’ve been logging every crash plus what i think triggered it for about three months. the pattern is wild - there’s like a 3-4 day lag between pushing too hard and the crash hitting. wednesday overdo it, feel fine wednesday and thursday, then thursday night i’m completely wiped out friday. once i spotted it, i tried to use it to pre-emptively rest thursday.

but honestly? i don’t know if that’s preventing the crash or just delaying it. sometimes i still get hammered anyway. sometimes i don’t.

it’s not consistent enough to feel predictive. more like i’m noticing a coincidence that sometimes doesn’t repeat. anyone else tracking this and actually finding patterns that help? or does the 3-4 day lag just mean you can’t actually catch it in time?

like, is tracking the data useful or am i just collecting numbers that don’t change anything?
