Harvest detection: Different results on subsequent runs

Hello,

We did 2 different L4C RUNS at the end of the season 2023 aiming to detect different agricultural practices.
For you information, we did those RUNS after the defined harvest end period.
We have noticed that for some parcels , we get different results depending on the run ( for example: there is a Harvest detected on one of the tehm but not on the other one).

Knowing that both runs were performed after the defined harvest period and that the system reports the first Harvest detected date within the configured period, we are surprised to get different output on the same parcel.
Neither the geometry nor the L4C parameters changed between both runs.

What could have happened?

For your information , we are using SEN4CAP 3.2.

Thank you!
