with my hand y abdomen to ensure I fill it well, I take a deep breath. Exhale as much as possible as quickly as possible from the abdomen, then the upper chest.

That’s a great tip, thank you!

It is kind of like monitoring weight. Watch the average tends.

I understand what you mean. the variability on both the PEF and the FEV1 seem higher than you’d like them.
