LIDO max shear value
Is there a maximum shear value for lido turbulence reporting. Previous threads suggest there is not an exact correlation between shear values and CAT categories but do not provide info on their origin. Just had moderate (genuine) turbulence in a shear area of 3 (although moderate was forecast on the SIG weather charts).

Just found this link which indicates that a shear value is a knot change for each 1000’ ...so the maximum would be what Mother Nature could throw at you. Also suggests severe turbulence likely when wind on polar side exceeds 100 knots.

I have never seen more than 9. But that doesn’t mean it’s maximum. Anyway I haven’t found this shear value very reliable. Sometimes it’s 9 and you get nothing and sometimes it’s 0 and you need belts to don’t hit yourself with overhead panel
