Plan Deferral Limit when Flat dollar exceed pay

So typically when a flat dollar elections exceeds pay, the whole paycheck less taxes would be deferred. if the plan deferral limit is say 80%, would the deferral on pay be the whole paycheck or just up to that limit? Obviously its a plan year limit - so I would still think the whole check would be deferred as long as it didn't make that individual's deferral percentage greater than 80% on the year. Thoughts?

Plan Language

I think if the plan says 80% is the max it is implicit that it is per pay period.  I don't see anything clarifying this in our (FTW) document.
