Despite your first thought, you're actually looking at touching those first 3 or 4 movements up to 3 times so make sure each movement is scaled correctly to allow you to do so. 20 minutes never seems to get shorter, but when you've got 5 movements, it should go a little faster, hopefully . . . Also 20, 20, 20, 20's going into the final day of 2019 tomorrow and then on to 2020!!!
