Talking to a master mason made me realize my mortar mix is probably wrong

I was bitching to this old timer about a retaining wall I did last summer that's already cracking, and he just looked at me and said 'what was your lime to cement ratio?' I didn't even know you had to track that separate from the sand. Got me thinking I've been eyeballing it for years now. Any of you guys actually measure everything out or am I overthinking this?

Yeah I read somewhere that lime makes it stick better and flex more.

I mean, people act like eyeballing it is gonna make your wall fall down tomorrow. I doubt it's that serious for a regular backyard project.
