How Long before Season 10 Repeats?

Does anyone know how long Channel 4 have to wait before they can repeat after the first showing of series 10?

I ask because they have just finished repeating Series 9 on a Friday, and rather than go onto 10, they are going back to 4

TBS (Atlant) is already showing Season 10. ~~~ Kathy

I just watch the S10 DVD's.

BTW, just bought myself a DVD recorder (a stand-alone one, not a computer one - than often causes confusion). :)
