Hello. Someone pointed out on my TAS of this that the best ending is actually considerably higher than we thought.

It's nearly 6 million.

Well that is interesting. I wonder what a real-time run of this would look like.

Nice discovery! It's helpful that the page also shows the actual money required for the sportscar.

I suggest we rename the Best End category for GB to Sportscar, for clarity. If anyone is willing to do RTA run attempts for the jackpot ending I can create a new category, but that may cause insanity. Any thoughts?

That sounds like a good idea to me.
