I agree that your ROI will drop as you play more tables. 2 or 3 should not really hurt your ROI but 6 or 7 will. It becomes a simple math exercise... is it better to be 6% on 8 tables or 10% on 3 tables?I don’t see much value in multitabling MTTs. Play one higher buy in tournament or if you are comfortable st the buy in level you’re at, just stay there. But it would be better to play one FT with all your focus than play badly in two FTs and get low places. Play well, play for first and play with all your focus and you’ll do better and I think find a better overall ROI.
