Balearics here we come - (day 6 sailing)

Our boat recorded 22knots of wind for a couple of hours and yet this app says we only got max of 11, how can it be that far out ?? The sea was a bit of a mess for most of the journey even once the wind died to nothing Mark though he’d press a button to see what it did - we went around in a big circle seeing as he’d disarmed the autopilot and he hadn’t realised 🙄🙄🙄 Anchored up in Portanax back on Ibiza for a few days
