Stuck in a Quagmire with Tactics Trainer !

   I appear to be stuck in a quagmire with Tactics Trainer and the timer appears to be the issue. I managed to get back up to 1200 (1196) after a couple of months on my 3/5 free problems a day but, recently dropped about 80 points.

The problem has been trying to solve the problem too quickly, in order to get a good or even a positive score and this can result in disastrous consequences. 

I could solve over 95% of these problems without a time restraint (big issue with an older guy), do you think there should be a time penalty on these problems ?
