...and therefore, One Shot mode is pointless with back-button focus since the back button will not fire the shutter?

For now I'm in AI servo all the time since I lose that One Shot functionality. But a few seem to feel one shot focuses better on still objects than Servo, and don't even mention the automatic shutter firing. Like it just uses a different focusing method/algorithm.

Can anyone confirm this? Or is everyone pretty much just guessing? I see no reason to go out of AI servo unless the shifting focus bugs me and I prefer BBF that picks a focus, and then stops until I release the button and press it again. So far, it doesn't bug me.

Another related question, any issue at all firing the shutter mid-focus? Can this actually make things blurrier? I tend to fire while the back button is still pressed, because in servo mode it's constantly updating, and I want as little delay as possible between the most recent focus and the firing of the shutter.
