HI
Number of tables is highly personal and depending on what you are comfortable with.
Games per hour, the same answer applies, you can check sharkscope and with some math you can figure how many games per day/hour plays X or Y player.
For turbo formats I would manually register, probably at the hypers top regs have that sort of software, however in these days I think its quite uncommon to register without checking the lobby, especially in higher stakes.
