For example, you don't really need 4 for something like https://gritroutdoors.com/canik-mecanik-mo3-6-moa-red-dot-sight-pacn1103 even with a magnifier probably. But for a 4-15x50mm I'd want all 4 probably

It holds okay in my experience, at least lighter scopes/small reflex sights. I'd guess if you going with something bulkier you'd want to use all 4.
