1st, if you have 70% in consistency, you can lower the precision to 70% (or 80% if you really like to be able to touch the lines on most of your serves).
After, be sure to have 780 points left in your character sheet, else the game engine will lower your skills, so it could be the reason your 1st serve ratio lowered.
Lastly, even with a good average 1st serves %, you still can have some bad sets sometimes.
