all levity aside, this is excellent advice.
I had a few jamming problems that resolved when I noticed that I only had the jams with film that had been in a reverse-wind camera (they don't all, my XA and Ricoh 500G just wind straight for instance.)
Once I learned to let the film "relax" for a day in the cassette, I had no more problems.
I found it also depended a bit on the film type. Some bases seemed a bit more prone to holding their "reverse curl" than others (Fomapan was a particular culprit for me)
