When first starting out, to make things simpler at the tables so that I can also take other things into consideration in the alloted time, should I first start out memorizing my hand odds exactly, or just round them for ease. And if I should round them, should I use the conventional technique of rounding anything that's X.5 or greater up, or else round the number down (to get the final ""X:1"" format)? Or, should I use another number for the rounding of hand odds (X.1, X.2, X.3, X.4, X.5, X.6, X.7, X.8, or X.9)?
My main concern is that I would like to know if rounding is that detrimental to a player that's just starting out... but, I also do not want to make too huge of a mistake of calling too much or folding too much each time. I imagine that memorizing the exact hand odds is the best way, but what is the conventional way to do it? I guess I'm looking for a way too fudge things that's a little more precise than the rule of 2 & 4 (although I would still use the rule of 4 for allins on the flop, since there's still two cards to come & I'm guaranteed to see no more betting). I think the answer is somewhere online because I looked it up about 5 or 6 years ago, but I cannot seem to track it down by doing a Google search or searching twoplustwo.com or flopturnriver.com. When I get the chart sorted out, I will probably either use it as PC wallpaper or print it out and have it somewhere handy for online play; & then eventually, after I play enough hands again I will remember the specific hand odds column. But for now, I was just going to use approximations if doing that is not too harmful, that way I can make decisions quicker on the fly.
... Three specific scenarios that concern me are when I have either 4 (10.75:1 hand odds), 9 (4.22:1 hand odds), or 13 (2.62:1 hand odds) outs. Could I just consider those three situations as having: 11:1, 5:1, and 3:1 hand odds? Or, should I maybe round the hand odds for the 9 out hand down (and call it an even 4:1, instead of 5:1)?
