What percentage of top level GM games actually end in checkmate?

I was curious what percentage of top level GM games actually end in Checkmate? I have to believe they end in a mutually agreed upon draw or a resignation. Be curious to see numbers on this.

Well I know that at the London chess classic there are a few mates each year. I would say about 10% or less of those games are mate in that tournament.
