Windfinder website question

I use Windfinder all the time in season. Below the windspeed and gust display is a percentage. I don't know how to read that. Does 25 mean one quarter of wind is gusts, and 0 mean no gusts? They do have 100% predictions too, does that mean it's aleays changing? They don't say in their FAQs.
