Re-pairing before second clutch?

Does anyone out there typically re-pair their females before the second clutch?

Because corns can hold sperm for months (if not years), I have never bothered to re-pair my snakes after the first clutch of the season has been laid. When my females have had second clutches, those clutches have consistently been slightly smaller in number of eggs and slightly higher in proportion of slugs, and I have always just assumed this was typical. This year however, I have had 3 females lay second clutches that were nearly all slugs. I have a small collection which allows me to really focus on good husbandry practices, and have not changed anything this year. Perhaps it is just a coincidence but it got me wondering if other folks out there re-pair their females before the second clutch is laid, if so when you do that (maybe right after the post-lay shed?), and if that practice seems to increase the number fertile eggs that result. Thanks in advance for sharing. Neil.
