More than anything, what Ken said. For your final boosts, you cannot do the extra bonus boosts until day -0- anyways. Game won't let you. So, technically, you could boost from level 73 to level 76 anytime once new season starts. But those final 3 boosts from 76 to 79 don't appear until day -0- so most guides just have you wait then boost everything at one time.
By this point in a dot's build, 99.9% of people are light training to collect BT's for AEQ. Light training any skill that's above 1st cap is generally a waste of time as you don't get much training gains once a skill gets to 50 or more. So, you're likely light training those leftover helper skills... Confidence, Stamina, or some skill that's useful but not a required part of the build (example; Blocking or strength for a Speed WR to help with outside runs). Because boosting gives you ALG's, anytime you boost you reduce the training gain % for primary and secondary skills because they go up. So, while it's tiny bits we're talking (about training gains), most ignore this stuff. Me, I just hedge my bets and wait until day -0-. Never know when that .23% gain might be the difference between a skill rolling over or coming up just short.
