Pokerstove calculations question

Been watching a few videos lately to try and work on my limit game more and a some have been using pokerstove to evaluate equity during the game on hard decisions and something I noticed that got me thinking was illustrated by the following example.

Player was at a table in the SB and facing a decision so brought up PS and set hand1 to villians (BTN) range of 24% to give a little leeway on his PT stats of 19%.

Watching this I suddenly had the thought of if that 24% range is correct or should we remove the hands that would make up his PFR range to get a more accurate indicator of our equity. For example, in the previous case villains stats were 19/15, so given he was on the button and didn't raise couldn't a case be made that SB hand should only be rated against the bottom 4% of villains range as he'd have raised otherwise.

I know this doesn't take into account that villain is slowplaying a big hand in hopes of getting played at, but how often would a 19/15 actually do that?

Yes, I'm likely off-base here as I haven't seen this brought up before as a possible modifier when talking about PS comparisons but I can see it as being a possible valid technique so am hoping to get either a solid smackdown or a good discussion going :)

I believe you have the correct idea here. Obviously, villain is NOT likely to have a Top 10% hand.

I don't know whose video you were watching. Here's my guess on the thought process. This person is trying to demonstrate using correct pot odds to determine when to limp a mediocre hand from the SB. If he compares his hands to the Top 24% of hands, he's effectively overestimating villain's strengths or undervaluing his own hand. Either way, it's a conservative estimate. If the Stove says we have enough equity (barely) to continue, we know it's a conservative estimate and we can confidently join the action.

Of course, everything in poker is read-dependent, so we'd obviously avoid LAGG's and maniacs in the BB. But if the BB is tight, using this estimate for pot odds is both conservative and reasonable.

Yes. If I have a playable hand in a case like this, I will often raise it instead of calling for this same reason.
1. I probably have his range beat.
2. I make up somewhat for being oop postflop by taking initiative on the hand.
3. I have a little bit of fold equity.
