Strategy error

In the LT league race today my race startegy seemed to error.

I told my driver to pit after it rained for 1 lap but when it changed to heavy rain my driver didnt pit.  It wasnt until it changed to light rain my driver pitted immediately.  My driver pitted 3 laps before this whilst it was heavy rain  and he changed for another set of softs which lost me a lot of time. 

Later on in the race i pitted for another set of intermediates, and then the following lap my driver pitted for a set of softs! I should have been in the top 3/4 but after this extra pitstop it left me in 9th and i failed to get my prize money

My strategy was completely different to what i set out

I see the problem but can\'t explain it.  Everyone was affected though.  \"Heavy Rain\" was displayed but it wasn\'t actually raining.  The track was dry until lap 13.

Your other problem happened because your pit stop on lap 25 was to refuel while your stop on lap 26 was to change to dry tyres.  As far as I can see this all worked as it should.  At the moment the only way to avoid this sort of situation well would be to issue live commands.

In my last race my weather station forecast heavy rain for the last 15 minutes of the race. Heavy rain never came, and the forecast never changed once it showed heavy rain.  Is this related?
