My advice is: Do not try to use a HUD in live poker unless everyone at the table is doing it. If you all want to slow down the game so that you can track stuff, that's one thing, but trying to track stuff while the game is going at the usual pace is no good.

You have to enter a ridiculous amount of hands (in the thousands or tens of thousands) to gain any information beyond what your gut should be telling you already, anyway. That HUD data is simply not as useful to you when the cost to generate it involves you pulling your attention from the action.

I suspect you'll reduce your EV by paying attention to entering data and not to the flow of the table.

(From experience. I created my own stats generator in Excel. I used it for a while and discovered that it was a massive drain on my attention and that I became mentally fatigued over a shorter session from all the back-and-forth mental gear switching. Note: I love generating and looking at data tables, so I'm a decent test case for viability of combining these activities.)

WTF is "luck factor?"
No. I don't want to know.
Pretending that luck is anything more than an emotional response to (in this case) well-defined variance is another mental distraction.

Your poker skill will improve more rapidly if you only focus on things you can control. You can't control card variance, so there's no point in spending any mental effort on thinking about it. You can control your ranges, your betting lines, your session length, whether or not you are well-rested and have gotten daily exercise. These are tangible things which you can set measurable goals on. When you focus on this kind of achievement, you are miles ahead of a player who moans about "luck" all the time.
