Don’t be stupid. They don’t use the same calculation for subscriptions, there they do 12 months. Only for consumption spending they come up with 13 months of 28 days. They could have just done 30 days for 12 months if they were concerned about over estimating. Guarantee 28 x 13 gives better number than 31 x 12.

The year with 372 days has lower daily consumption spending than the year with 364 days... What are you even.

		Um what? You seem confused, they didn’t measure a year with 372 or even 364 days. They measured 28 days. And it’s almost a certainty that taking the average spend over the last 28 days and multiplying by 13 is higher than taking the average spend over the last 31 days and multiplying by 12.
