Train Tactics
I do 10 in the morning first thing and 10 in the evening. That's enough I think given other areas of the game that need time. Playing, by far, to me the most important aspect of training. I think you should "play - study - play", etc. Frankly I get tried of tactics even with just 20 a day - I average 120 a week so I do take Sunday evening off and probably another morning. Weeks when I play I drop down to 80 to 90. It has worked for me! Good luck.
