Schedule for putting 1 male with 2 females?

I am wondering what kind of schedule that folks that pair one male to two females use. I did three days with one, then three with another and I will now give a few days off before doing it again. Does that seem sound or am I asking too much from my male?

I pair for 3 days with female #1, 4 days off.
Pair for 3 days with female #2, 4 days off.

In hopes for two good locks per month.

Thanks for the response! Does anyone else do anything different?

I do 3 days with #1, 3 days off, then 3 days with #2 and 3 days off :)

I pair Sunday thru Tuesday and feed Thursdays.

If both the male and female refuse on Thursday I may pair a day earlier, but that does not happen often. The females rarely refuse unless in shed.
