Karl, I think we have covered the swellings that may occur during 
pregnancy and prior to a true puberty.  Outside of these situations, if 
a slight swelling occurs between a female's ddate and mdate, it will be 
assigned to the female's prior cycle, if I understand correctly.  
Therefore we are never in danger of violating the "no swelling size 
allowed before a cycle's mdate" because by our definition of a 'cycle', 
there is only ever one day falling before an mdate. 

So... the take away message is we will allow these odd swellings /after/ 
the ddate of a cycle but not /before/ the mdate of a cycle, right?  It 
sounds like I'm saying the same thing.  However, for our purposes, we 
are making them linear with a start and end point and where these 
mini-swellings fall within a 'cycle' makes all the difference.

If this makes, sense, I'll check back with Jeanne and we should be able 
to give you the OK on everything tomorrow.

BTW, where did the cycles_sexskins view go?  Is it out of commissions 
while these issues are being resolved?
