For some reason, such a guide hasn't been done yet, so I'll give it a shot. Tests done with Sana 707 juicer, fine screen, strainer used. Weighing was done with whole fruit (peeled where applicable); some juice was probably lost while cutting. Results might differ with other juicers / age of produce (old and dry will give less juice).

This section was getting too long. Anyway, I added a 3rd run category, which means running the pulp through the juicer the second time and seeing what additional percentage yield I get - which still happens to be a lot for the produce tested (ideally I'll retest all with the 2nd and 3rd runs). This juicer seems sucky tbh; I feel like everything should be gotten out during the first run. Maybe the Angel does it but I have no way to test it. A range means I did more than a single test and all the results were between the values given. UNS
= unstrained; the strainer / sieve got clogged, probably. So I just threw the clogging things in, which means there's going to be a little higher result than would be without.
