Amex Everyday Preferred Card - monthly boost calc

[PointLager]

Does anyone have experience on how the 50% bonus is calculated on category spend.

Example.
30 transactions, all grocery spend in first month. Total spend is $100. 3x grocery gives you 300x MR.
Is the extra 50% based on just base dollar spend or total MR earned. So either extra 50 vs 150 MRs for a total of 350 vs 450 MR at month end.

Thanks
