Hi,
I'm afraid that you are not able to create your own stats regarding number of different cache types found per day in Project-GC.
What you can see is you best score - it is in your Profile Stats in Some numbers section - its label in English is "Most cache types in a day:" -

The other thing is that you can take a look on a top list of finders with most cache types in one day:

I hope it helps!
Cheers,
