How many times can I convert training?

I know the answer is located somewhere on the game, but I can't seem to find it.

1st time is 10k
2nd is 2 credits
Does the 3rd cost anything ? Or can I convert a 3rd time?

From the wording in the training center it seems every conversion after the first costs 2EVC, so presumably that's how much a third conversion would cost. I dunno if there's any limit on how many times you can convert or not.

ive converted four times.
each time after the initial 10k is 2 credits

Thanks for the answers guys! :)
4 times O.o

i was very indecisive about discipline and then i wanted to breed him to mares in two different disciplines. he was a foundie if i recall, so it worked out :P
