      What did they mess up? Seems like a reasonable max combining life span of sperm with ovulation period (you said the math is bad and not the biology)

        If the sperm dies on day 5… How do the 2 ovulation days matter?

        Edit: spaced about bottom of Dad 1 4.5 or whatever days before, then the other dude at very end.

          You can get pregnant the day after ovulation.

          Also, since there seems to be a lack of basic reproductive knowledge here, identical twins come from one egg, fraternal twins come from two eggs, which can occasionally drop on different days, further extending the fertile window.

          Guy number 1 blows a load 5 days before day one of ovulation and guy two blows a load 48 hours after ovulation starts (tail end of the period)

          [edit] more clear language on timing of second load
