Proposal to Improve Quickbattle/Autobattle

Instead of the current quickbattle system (which relies heavily on RNG in scenarios like the Hydra), why not implement a system similar to Reverse: 1999?

In this system, the best time/damage/score, etc., is recorded.
When using automatic/quickbattle, the game simply repeats the recorded run.

If a player wants to improve their run, they can do it manually or in autobattle, and then overwrite the "saved run."

What do you think?
