If you can't calculate a gross estimate of the x-wind component from the raw data then you shouldn't be alone in an aircraft! Even as a 'low hours PPL' you've got 40+ hours and should be able to do the maths by now. I suggest you sit in working out x-wind components for an hour until you can do it quickly and easily. 30 degrees off - use half the wind. 60 degrees off - use all the wind. Getting close to limits - do some harder maths. Lets not change international aviation standards because somebody can't be bothered with maths.
