I remember the region referring to our original purchase of 14 vehicles as being 2 maintenance spares + 12 in-service vehicles, with 8 minute headways. So your math tracks with the reference to 1 additional vehicle being adequate for 7 minute service. I assume they meant 13 in-service vehicles, with 7.5 minute headways.
Whether 2 maintenance spares is actually enough is of course another question.
