While all three used a submission only format, matches in Metamoris without a submission finish were immediately declared a draw. EBI and SUG both employed the overtime system pioneered by Eddie Bravo. Check out the rules video for complete details.

At StrikeScoreMMA.com, we previously looked at how the EBI ruleset promotes an action style. The lack of an instant draw, and more liberal regulations overall, appear to encourage fighters to try to finish the bout inside regulation. The result in a much higher regulation submission rate in EBI compared to the 2015 editions of ADCC Submission Wrestling World Championships and IBJJF World Championships (Gi and No-GI).

At EBI 7, 10 of the 15 matches ended via submission before overtime. After incorporating those numbers into the promotion’s overall numbers, the regulation submission rate stays constant at 72 percent.
