TOO, perhaps you could pass on your in-depth knowledge of weather avoidance and aircraft to the pilots who routinely ask or indeed just turn on their own initiative to avoid flying through wx. They are obviously not as switched on as your good self, and it would make my job a lot easier if nobody wanted to avoid anything. 1% of the time, try probably 20% of days on average I'd guess throughout the year, or indeed weeks on end depending on the season.
