In PT2, I have a database for my play and another database for mined hands. Every million hands or so, I swap out data mining databases, mostly because the mined data is now a bit stale, but also because I don't want my mined databases getting too big, and I wasn't sure whether PAHUD cache likes many different databases feeding into it. My main point is It makes a huge difference when I am doing PT reviews, only having PT need to worry about my hands.
I've only put my played hands into PT3. I know that PT3 can handle much larger databases than PT2, but is there still merit in having separate databases for data mining and actual play?
I'm guessing that the HUD will prefer a single database, but not sure how much difference it would make. For reviewing my own play, how much difference will having millions of mined hands in the database make, do you think?
If I keep one database for everything, will it be pretty easy to purge hands say older than a year that I was not in?
