How often do you pinch flat?

[cwtrials]

I'm curious what is considered normal for how often you guys pinch flat.  Watching some of the group ride videos, it seems like some of you guys are replacing tubes a few times a ride.  

I started riding the Ridenow TPU tubes; cause the weight savings is ridiculous.  But patches have all pulled loose.

Nothing worse than a bike you need to ride gingerly. 

Changing a tube normally ruins your grind so its just not worth running a light tube or an XC tyre to save a couple of grams here or there.

I have found the TPU tubes are more pinch resistant than a standard tube.  They just don't take to patching well.

Normally I try to keep my PSI high enough I don't pinch; but was curious how often other people are.

haven't got any pinch flats for more than a year after I kept my tires at 38-40 psi, and some impact absorbing body language. But now I got few joint pains.... I just switch to TPU weeks ago, but my joint pains got worse....😁

I use a der Kaiser with a 3 inch dh tube. What are pinch flats?
