Percentage of peak time trains via Falkirk High on time: FOI release

I make a daily commute from Edinburgh to Glasgow Queen Street via Falkirk high and back. Unfortunately this service is often delayed or cancelled. 

Please confirm precisely what percentage of the scheduled morning and evening peak time trains (either way) on the Glasgow Queen Street - Edinburgh Waverley (via Falkirk High) line have left and arrived on time in the last 6 months
