Bigger is Faster and Cheaper: The Surprising Economics of Snowflake Virtual Warehouses

Hi, regarding "This means, for example, that as the warehouse was scaled from an X5-LARGE to an X6-LARGE, although the query performance was improved by 60%, the cost was increased by 100% leading to an increase in query cost." but metrics table shows query performance was 100% (60s down from 2mins) while kept same cost $8.. so bit confused as: metrics table shows - double performance with same cost: X5 2 mins $8 X6 60s $8

But your paragraph tells: query only improved 60%, and also it says cost doubled.

Can you please explain if there's a typo anywhere and/or where am I misunderstanding metrics table vs your paragraph? Thanks in advance ☺️
