Gotcha, feathering the valve on the bad side is a good skill to have and practice.
As for routinely looking for a small leak, I’ve never done that or seen that. What would you do if you were diving in single or doubles back mounted. When diving sm, it’s easy and essential to do a bubble check b4 diving. You can have a buddy do it in other configs and I normally do.
Maybe one of the downsides of solo diving? And maybe has some merit when diving solo. But a small leak you don’t notice is probably not that important. And can be dealt with after.
