What is the official stance on maintaining your mastery of earlier elements?
When I first tested myself on foundation, I failed as many others did on some of the high volume elements such as ABH and HBH. Several months in, I now finished F4 on some elements and am not far from finishing the others.
I tested ABH and HBH again and only managed to do as much as when I first tested these.
Should I work back up to mastery and try to preserve it considering my training time is quite limited at the moment?
