SHOCKED - how much does a wetsuit/Swim Skin actually gives you!

I have been meaning to test what time advantages you actually get from a wetsuit and also a swim skin - against just a pair of swimming trunks/swimsuit. The time advantages really surprised me, especially the swim skin (orca RS1). Watch the short film to view the exact numbers.
I tried my best to swim the exact same course every time and at the same effort - which was FULL GAS. At the end of the film you can see a full break down of the times/splits.
