As someone who has an infant in the house, how - if at all - have you adjusted your multitabling? If your wife needs help right this minute, you will still need a little while to sit out (if you're waiting for the big blind) or you have to lose a little bit of EV by sitting out right away. The more tables you play, the more significant the loss of immediate sit-out is how I'm thinking. (I'm obviously not talking about emergencies - I have no problem just getting up and timing out if something serious just happened - more of the "I forgot the diapers downstairs and I can't leave him here, help!" variety.)
The chapters on multitabling (I hadn't actually gotten to them before wanting to ask this question, but I skimmed them to make sure I'm not asking something answered in the book - apologies if it's mentioned elsewhere but chapters 15-20) stress something important: Only add more tables if your $/hour goes up, which I obviously agree with. My view, though, is that it doesn't take much of a loss in edge to wipe out any profit added by a new table, and since most poker is played at tables where our edge is very small to begin with, adding another table can quickly become a losing proposition. My question, basically comes down to this: Do you think you have skillsets and natural talents (whatever that is) that enable you to play as many tables as you do, and that people should be very careful in emulating this aspect in your poker playing, or is maximized profit playing 15 tables something anyone can do with (a reasonable amount of) practise?
