After a Visit to the White Pages

I have a question concerning oxygen exposure. I TIG Weld custom aluminum T-Tops so I have Argon everywhere. I have had the practice of filling my carboys with argon before racking, my 6 gallon glass big mouth bubbler (where I filter my wine for bottling), any carboy actively fermenting but will excessive headspace (air lock is bubbling), etc. Is this practice of keeping oxygen exposure reduced excessive? Thanks

A lot of folks use Argon and other non-reactive gases. It works.

I don't use it for large headspace, because I can't see it.

Sounds crazy, right?

Well ... logically speaking, I realize if you pump enough argon into the headspace, it will displace the air. But I have no idea how much is enough, and I have no way to prove it. OTOH, when I fill the headspace with a compatible wine, I know 100% what is in that head space.
