theoretical question about difference between transmitting stations in Bit-Map Protocol

i am wondering about the difference between the transmitting station in a bit map protocol.

for instance, if we have 8 broadcasting stations numbered 0-7, and the racing (contenting) time is $$t_0$$ and the length of each broadcasting frame is $$20t_0$$

then, will there be a difference, if for instance, only station 0 wants to broadcast in each time slot and all of the other stations doesn't want to broadcast at all(at any time slot), or the exact same thing if the only station that wants to broadcast in each time slot is station 2?

is there any difference except of the station number(both seem to be low numbers)?
