I never had a problem with this.
I didn't have to make round trips to the PC since I had an HM Slave and only caught what I wanted to use, therefore I never had to deal with the long saving times. Rotating your team pre-Gen 6 (less so in Gen 5 due to scaling) is detrimental, anyway.
Even when it did "save a lot of data", it never bothered me because it was just a few more extra seconds.
