If you can achieve mastery when practicing under difficult conditions (i.e., lesser time than allotted), then you can surely excel and feel confident, relaxed, get in the flow when you have beneficial conditions

Work will always expand to fill the time allotted.

-Even when I added the extra 50% to my practice, it still took me more than the time allotted (52 minutes.).

-Scores are fairly consistent unless you're rushing haphazardly. I found that when I reduced my allotted time from 52 min. down to 35 min., I began to receive the same score per section as before.

Just some things I found helpful!
