I don't believe you can simply equate your dynamic time from static times. Simply put, it differs from person to person. I personally suck at dynamic with fins. For me, when I had a 2 and 1 half min hold, I do remember doing that 50m swim I was talking about above. Right now my holds have doubled, but my dynamic with fins hasn't gotten better. It might even be getting worse. Dynamic without fins is another story.

Cheers.
