Very successful with slight changes here and there depending on the matches etc.
Players improving much better, far better training ratings, no complaints, barely any training injuries. The intensity/rest does need lowered from double to normal during the season.
The recovery for no match weeks is to manage the players injury risk, it doesnt have to specifically be just after a match, and nothing more. It's a spare slot so why not? Also most of my players are away on international duty during this time so only about 8-10 players will be doing this training week.
The double extra-curricular is moral boosting for the squad and for your supports confidence. As I said, you've got spaces so use them for something other than the training sessions that don't work.
Edit - I will add that I remove the match reviews once the tactic is fully familiarised. It is replaced by a rest session as full familiarity with a tactic after tinkering the first few games comes during the double game weeks so to help with fatigue.
