One of my secret weapons. I use it extensively now at .25% but ran it up to .5%. I researched the sodium contribution and IIRC the sodium contribution or saltiness is not linear and that mirrors my experience so IMO no need to scale back on the salt. MSG is more of a mouthfeel than saltiness thing known as umami. I would call it a flavor enhancer rather than a salt substitute. Glutamates are pretty much in everything especially sausage and those that have labels claiming no added msg are using lawyer speak and cheating using things SNIP some of the food additives that contain high level of free glutamates: monopotassium glutamate, glutamic acid, glutamate, vegetable protein extract, gelatin, hydrolyzed vegetable protein, Accent, hydrolyzed plant protein, sodium caseinate, calcium caseinate, disodium guanylate, disodium inosinate, senomyx, textured protein, yeast extract and autolyzed yeast.
