What do you think about the BLIPMAP Buoyancy/Shear Ratio parameter?
Is it accurate that less than 7 makes the day difficult to work?
I have found lately that this seems to be true but my sample size
is small. I am in the northeast US. Location is probably a factor.

The best thermals on any given day have better buoyancy, so better B/S ratio.

Days with a lot of shear put an absolute premium on thermal selection. I'd put the number where things start getting choppy at around 5.
