Skate Sharp Tracker

Acording to Skates.com ice skates need sharpening around every 20-30 hours of ice time (depending on the ice and the skater this can vary between extremes of 10 and 40). This sounds about right, though usually mine get done when I realise I don't have enough grip any more. Hence this idea.

Things it needs to track:

• when you last sharpened your skates
• how many hours ice time you average between sharpening

Optional extras:

Depending on how nerdy the user wants to get, what kind of ice they're skating on, or even what they're doing when skating as this might have an impact.
