frequency of Squeezes How often do they come up

In Mike Lawrences excellent software Counting at Bridge he estimate that squeezes occur in 1 out of 30 hands. He also says that simple squeezes make up the vast bulk of all squeezes.
1/6 (16%) is vey different from 1/30 (3.3%) even if both are approximations.
Roughly how often do squeezes occur?

I think at a local club, "pressure" adds up to as much extra tricks for me as operating squeezes. Pressure (or a light draft) leads to operating squeezes that never should have existed. So in a bad field, there are more squeezes.
Thanks,

I wonder if the frequency of squeezes and pseudosqueezes in actual play could be queried with BridgeBrowser ?

If I interprete your statement correct, 1 or 2 of the 7 hands
you are playing as declarer involve squeeze considerations,
I would say, this sounds like 1/6.

Here's another hand:
Playing in 3NT you receive a minor suit lead. After a heart to the king and ace (say) you will make 11 tricks on a simple squeeze if the same hand has 5 spades and 3 hearts. Pretty unlikely, but it might happen.
If you count both of these hands as 'possible squeezes' then I would say they are at least 1 in 6, possibly more often.
If you only count hands where declarer correctly decides to play for a squeeze, and is successful, then the occurrence is much less, maybe 1 in 30 is about right.

I thought it was because we lead more aggressively and thus break up more squeezes

probably not, but you could ask Stephen
problem is you can set constraints for hands, like 4-4 in majors and if you do a search it will only show you the hands that fit that criteria.
So most likely you would have to do a general search like say auction goes
1♥ 3♥
4♥ First, then
do a search on the same auction where the defenders have specific holdings.
then divide the second by the first for %
might actually be easier to a simulation, then pick hands from simulator that fit for defenders hands.

Most of the time a finesse will be as good or better than a squeeze so for me that is not pertinent even if the squeeze work and the finesse fail.
Often you are in a pretty hopeless contract and are looking for a lucky break even if the squeeze has little chance of working its pertinent because at the other table the guy might be in the same contract and find the squeeze possibility.
For instance, he doesn't like being used as a human shield when we're being shot at.
I happen to think it's a very noble way to meet one's maker, especially for a guy like him.
Bottom line is we never let that difference of opinion interfere with anything."

So if you want to improve, watch out for more endplays then squeezes.

LOL!
That was my take also on reading the book.
A double squeeze comes up 50% of the time. And it usually works

I think there is a difference between a squeeze possibility and a squeeze.
Let's take a one-sided squeeze, one could say that a squeeze possibility existed on this hand if LHO holds both threat cards.
However, it is not actually a squeeze unless LHO does hold both threat cards.
So, there could be a 2-1 type ratio of possibility to actual squeezes.

Sounds about right.
Do not underestimate the power of the dark side. Or the ninth trumph.
