I agree. More specific training for the movements being tested, but limit any new types exercises, stretches, mobility work, especially if n the 7-10 days before. Also, as I mentioned earlier, it f you do a good taper before, your performance will also likely increase. I’ve read in some endurance training manuals, that it can take up to 7-10 days to accrue positive adaptations to endurance training. So the week before, you might consider decreasing intensity/volume, but potentially keep the same number of training sessions. Also, if you don’t already, add in some relaxation/meditation/parasympathetic breathing exercises. If you go into the tests fully recovered (muscoskeletal, neurological, and enzymatic/metabolic), you should see significant improvement from what you were experiencing during training.
