Snorvich, thank you for all your help on this. I did read the other threads too but just wanted that extra bit of 'yea you're good' and considering you kinda lead the charge on the other threads, I feel fine
As for the 'it only takes a few minutes'... sometimes I'm not even here for those few minutes. Sometimes I'm already at work at 3:30am, and other times I haven't even gotten home by 11am from working the night before. It's the nature of my job, but I can at least always count on being home around dinner time, as the work is either scheduled way before then and I'm done, or not scheduled till later that night before I can begin.
And just to be clear... I should be good as long as any transfers take place within 82 hours of each other.
That gives 2 hours to get to surface, the 10 hours to encyst, and then 3 days (72 hours) to hatch and become infectious again. I would be sticking to 72 hours (pretty much every 3rd day 7pm) to be sure I can stay with an exact time cycle.
