3.) 88-94% is high end- Body is burning zero fat at that level. Likely not burning much food either. You are burning all glycogen at that level. Not to say that there is zero long term fat loss form this type of training. But the fat burning occurs because you are burning more total calories per day- not during fat as fuel on the ride.
My RX would be to make sure that you have enough carbs in your diet to support your training and recovery. Make sure glycogen stores are full when you are doing training in the 88-94% range.
It sounds like your durations are not huge so little tweaks should go a long way.
You might also look at your carb choices. In a best case scenario they should be complex carbs and not processed. Rice and sweet potatoes are great sources.
Pasta is pretty much just like eating wonder bread-
