I don't put much stock into the test. If I was you get a clone and grew her the best you can and enjoy. I have had mine tested 1x... I got 26% but it means nothing to me. The test are not accurate IMO. 1 lab gives you 20% the next gives you 25% it's all bullshit. I only care about the Terpenes profile... Some of the people I gave the cut to got 19% ..dano doesn't know what he is talking about cali has produced some of the best cultivars there is....There are more poor growers then great growers. Commercial growers wont have the same quality as a small operation will. They want Yield over quality.. They just cant put the time needed into ea plant. Everything gets the same treatment, Same food, Same lighting, Same environment.. Makes a huge difference when you can treat ea plant individuality... I notice when I have too many in flower.....
I think you're not understanding lab testing. From the same batch one bud can absolutely give you a 20% test and another a 25% test and both can still be accurate. There is definitely that much variance from bud to bud, more even.
It does seem unusual to me that you believe all bud grown commercially is automatically bad. Because greedy big business? lol. ok.
In my experience sacrificing quality for yield isn't a real thing. You know which plants produce the best quality? Healthy ones. You know which ones yield the best? Also healthy ones. Sure, different commercial grows vary in quality. But the goal of a personal or commercial grow is the same, healthy plants. If you don't believe it's possible to grow quality bud and make it commercially available than I suggest you get some more industry experience before commenting.
So yes, perhaps HPLC testing is all make-believe.Or perhaps the problem is a lack of understanding of science. I'm pretty sure every analytical chemist in the world would disagree with you, but what do they know?
Interesting how the labs are all testing the cuts from one source at around 30% and all the others closer to 20%. It would appear to be some sort of pattern except of course chemistry isn't a real thing so I guess we should ignore all of that science stuff and instead make decisions based on what some guy told you.
