Summary

Steps to reproduce

Create the experiment with the joblist in the experiment.

What is the current bug behavior?

If the chunksize is changed, it only takes the last month of the chunk to compute the splits 🤔 and only one month is created (not a 2-month-long chunk)

That is:

for chunksize 1 starting on November, I get a month of 30 splits. That is ok.

for chunksize 2 starting on November, I get a single month of 31 splits Instead of a 2 month-long chunk.

What is the expected correct behavior?

I would assume that with chunksize 2 I would get a single chunk of 30 + 31 days.
