Minor discovery regarding Hyper Recovery; After intensifying and (upgrading with a star) I found out you could actually get a +99 recovery
before hitting the sweet spot in the gauge, using the H-Rec Bonus Supplement to expand the zone.
Obviously using less turns to get the max recovery is more efficient (need to be thinking in term of points gained/turn here) so this opens up more use for the Bonus Supplement.
EDIT: I've created some illustrations to help explain this point. The thing is, the visible H-Rec gauge only explains the
availability of Hyper Recovery (ie "If you rest now, you can/can't get a Hyper Recovery") and not the amount. Those two gauges are independent of each other and fill up at different rates. The following diagrams are not accurate but I figured it should make it easier to visualize.
Before Training Upgrades:
Amount gauge is hard to max out, over-training is necessary to get a good amount of Hyper Recovery Bonus.
After Training Upgrades:
Amount gauge becomes easier to max out, thus you can get a good H-Rec Bonus in fewer turns.
PS About the "inaccuracy"; I think the length of the gauge doesn't shrink (cf the gauge will not fill up as quickly if I practice something that's not upgraded), but rather the upgraded practices fill it up more quickly. Think of a fixed-length Amount Gauge that fills up at different rates depending on the type of practice. If you want to get even more technical, there are two - one for Strength and another Quickness. Again, diagrams are for demonstration purposes.
