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. Also, the measuring cup starts from 200ml and only shows increases for every 50ml, so the data points are kind of by eye especially for the measurements under 200.
