It's like that common misconception about the testing pyramid. The reason it's smaller at the top isn't because you should have numerically more tests at the bottom then at the top. It just shows that if you're doing a higher level test, you're also testing the layers below this. As an unrealistic example: if you'd have 1 IT and 1 UT, you'd still have double coverage at the bottom. You're probably still gonna create more UT then ITs though, as they're easier to write... so this is probably more academic pedantry then anything insightful
