I wouldn't call it a cubby ace, I would call it a nice second/third/fourth shot.
I'm not trying to be confrontational but why in the world would you score 5 rounds at the same time? I mean anyone can do anything they want, but to what end would you do 5 rounds at the same time and keep score? These wouldn't be rated or official rounds so why? Personal satisfaction? Practice? Because if you were throwing 5 drives per hole there is no way those would be official rounds or even rounds that would count in any way.
The fact that doesn't change is this... any additional shots you take after the first shot become progressively easier. If you came to me and said I shot 15 down and I threw 5 drives every hole...then I would say, no you didn't...sorry.
