Lol, I still need to seriously TA the bosses. I just don't like the bosses of this game at all <_<
Anyway, there's absolutely no reason for you to be sorry or anything, it's what competition really is. In fact, I have to thank you for actually telling me where the last 10 rings are. I max have found out myself, but this way it probably saved my a lot of time.
And no worries about the 0 points, I'll get these ten rings soon!
Breaking what people think is max is like the best thing ever. I remember very well what happened to the Final Rush time records, with the records going down by over 8 seconds!!
Anyway, I suggest you starting with DR1 as a nightTA, because the record there isn't maxed out at all yet, and it's a pretty easy and short level.
