And do you think it makes much of a difference mate and if so wot sort of numbers whould you be looking at for a really good sesh ??
I think a lot has to do with confidence and what you notice when you had s good session or blanked.
I find that if the biometric pressure drops below the 1000, it's fish less, if it goes the other way 1030, again it's dead, but I try to look for 1018, on my records of big fish that was the pressure give or take a few bars that I caught on.
Not saying it's the only thing I look at, from the moon to the tides , wether they building or not. I have done well on trends that should not have caught really but that 1014 to 1020 is the best ,
But if you look at the graph at the bottom, I look at the pressure how it goes up or down , if it has a sudden drop say 1025 and start falling and the forcast shows it slowing at 1003 that will tell me when it's best to fish on the drop or reverse.
Many people don't believe it affects fishing , but Monday again showed , the morning was great fishing, but couldn't go, but the pressure dropped so fast while I was fishing from 1010 down to 987 in the evening , I knew it was a blank, and it was badly with others also blanking.
Sorry for the long reply wacker
