Apprenticeship Agreement - new version

This still says 20% in the wording - so I have amended to say an "average of 6 hours per week for the practical period" has everyone else done the same and is this OK ?

I wouldn't recommend changing the notes as the requirement is 6 hours out of a capped 30 hour working week, which is 20%. 

The new minimum off-the-job training requirement for a full-time apprentice is 20% of a 30 hour week (even where the apprentice works more than 30 hours per week for an employer); this equates to an average of 6 hours of off-the-job training per week.
