Possible for db to solo pb?

PB is 65m exp last time I checked (did it change with chaos?), that's only 21m. On top of that, there is party bonus exp.... She has co and there is another character on the left side of the map.

EXP splitting..?
Also I hate the whole argument about how "there's someone else on the map so it isn't a solo"
A solo can be defined as many things, it means one. So it can either be:
One person doing all the work (Multiple accounts, different computers, same person)
One person attacking alone. (People helping them buff, but not attacking)
One person by himself in the map. (What you're suggesting, more than likely)

If there was something like 2minutes left on the timer it would be a little more believable.. not with 41min left.

Okay bro. Count how many people are in the map that are actually visible (I only can see two) and it's still impressive to have 41 minutes left. I doubt you can bring 2 people into the map and finish killing it without dying (echo didn't run out) and finishing in under the hour.
