I've recently been finding myself using MediKits more often, likely due to the lack of competent Doctors and Servant Remotes in Ariadna, but I've encountered only limited success with them. I'm not sure that I should even bother trying to make use of them.
It's always difficult to work out odds on the fly, so I thought it'd be interesting to spend some time calculating some different probabilities so I can be better informed for future games.
Warning: There be charts ahead!
