When I saw the “weight goal” link in the app for an exercise, I thought this is how it worked.
Since the estimate is formulaic, you could work backwards to prepopulate the weight targets for a given RPE by setting the 1RPM.
The use case would be looking at your history, you’d see last week you hovered around a e1RPM of 300. But it felt a little easy, so you want to step up a notch. So you could set the 1RPM to 310 and it’d fill out the template for your targets for this exercises RPE/reps. Could even have it start set at your last days e1RPM.
This is basically what I’m doing. But takes the extra steps of guesstimating the new set targets for a given rep count.
