No intervals detected on new sessions

Hi,

intervals.icu has not auto-detected any intervals on my new sessions since Monday (21/9) e.g.
https://intervals.icu/activities/4093405359

It had been detecting sessions up to Saturday (19/9) e.g.
https://intervals.icu/activities/4083757292

If I use “Analyse” and enable both check boxes I get intervals similar to the previously auto-detected intervals.

Is this a planned change (in which case I’m happy to use the “Analyse”) or is something else happening

Regards
Sean

Phew got a fright when I saw your post but things are working. That activity has lots of subtle tempo/threshold efforts that are just a bit too short to be picked up as “intervals” by the detector. It has some heuristics like “a zone 3 interval must be at least 170 seconds”. It also won’t count a short sprint unless you did 4 or more of them.

I have a long outstanding todo list item to add those knobs to the “Analyse” dialog for tuning this sort of thing.

Thanks David, I blame the Zwift Gravel Grinder workout plan I’ve started, it does like to mix it up… :slight_smile:
