Leho, you reminded me of a % story. About 30 years ago when I lived in Wpg, there was a stormy rainy night. It rained so heavily that our flat 2AC lot had about 5 cm of water everywhere. We could not sleep well of course because of the storm and rains. When I turned on radio at about 7h, I heard that there is a 70% chance of rain today!! We did not have a minute without heavy rain since the midnight and it did not slow down until noon. I was laughing whole day about that 70% chance of rain, they repeated it whole morning and I think there was a break in rain late next evg.
Point is, even the % can backfire a bit sometime. Jirka
