Data used in updating bazzite?

Considering using either Bazzite or PikaOS,

Bazzite strikes me as much more polished, professional, reliable, stable, more likely to continue to receive maintenance, less likely to have problems with, compared to PikaOS

However, I'm concerned about the bandwidth. I have a limited amount of downloads per month.

Can anyone tell me how large the updates for Bazzite might be every month and how large they will be for PikaOS?

Is it fine to use bazzite, maybe only updating it once every month or two, in order to conserve internet data?
