Electron Data Usage per function call calculation

Does anyone know how to calculate how much data each function call / POST takes up? I was hoping that I would be able to determine this by going to BILLING, checking the total, and then calling a function. However, the data usage graph doesn’t seem to be updating at the moment.

Basically needing to see how many function calls I can make to the device before reaching different breakpoints in data usage.

Thanks. Alex

The billing page only updates for me every 24 hours and sometimes sooner. It’s supposed to update every hour.

The billing only has a data resolution of 0.00 MB digits so I think the only way to do it if that’s all we have to work with is to run function calls and then wait for the billing page to update at a minimum a tenth of a digit.
