Under EASA .....
It always has been 200 hrs IF time (if you are an FI) before you could do the upgrade course to teach IR!
I know in the old CAA days you used to be able to count 4 hours for every 1 hour of IF if by sole reference to instruments, not sure if that is still the case with EASA rules??
Quite agree with Bose-x, how on earth can a VFR trial lesson be counted as IFR!!
