Swim Cap Advantage?

Apologies if the answer to this is in this forum, or on the internet in general, but my searching skills are obviously lacking. So, I keep reading that swimcaps reduce drag. What are we talking about here - a 1% advantage over not wearing a cap, if all else remain equal? 2%? If I wear a cap, could my 40.5sec 50m (which I have done 3x) be sub40? :)

  • The great Popov never wore caps, even though he may have been a tenth or so faster with one. He is still the fastest non-techsuit swimmer after 2 decades. Unless you're counting jammers as tech suits, he's not anymore. If you are counting jammers... I highly doubt any elite swimmer is going to do a tapered 50 free in a brief anymore, so that makes it a bit of a moot point.
