There is for sure leeway of a couple players. I had a run of weeks when my only Aglaia run would be monday night an hourish before reset. Those runs were especially rife with people doing this, because they could literally stop you from clearing for the week if they trolled efficiently enough. So what ive started doing was purposefully standing on the wrong side, right at the line. Everyone else arranges themselves, and most weeks i dont have to move(i will rather then wipe us of course). If i see anyone running accross the line right at the end, im ready to hop back over and re-fix it. Not perfect, but i havent been successfully trolled in weeks. Of course, now that ive said it im due for one.
