Well honestly something doesn't add up. Let's break it down a bit.
First, your source is Short Path concentrate. That should be a barely viscous honey like material that is virtually all cannabinoids. It should be decarbed already as part of the distillation process.
Then you go on to further decarb this for 4 hours. This is because there are still bubbles.
Then during the 4 hour process, something is evaporating and re-condensing on the glass. You state it is oil. Both THC and CBD would dry out to white crystals - powdery - if you were somehow able to separate these out in this process. CBG is a pink semi hard blob. THCV is a brown glass like substance. None of them are oil.
Then you have the bubbles that continue after 4 hours. I think you have something other than a SP distillate, or there is something else added back in post process.
No, you definitely do not want to declare for 4 hours. Even if it is not cannabinoids collecting on your glass, you are in fact destroying them with a 4 hour decarb. This I know from my own time and temp decarb testing using TLC to measure cannabinoids. I have a video series about that here somewhere.
Really what I need to help you is more info. Post some pics of the source material, the process, and the resulting oil and I'll try to figure it out with you. You also could tell us more about the source. Are you making it or buying it? Is there a label, or a website we can look at?
Need more info to help you, but if you did not decarb for 4 hours, we wouldn't see the oil. Just the bubbles. So what is causing the bubbles is the real question. My guess is terpenes or something is added back in post distillation and that is your issue.
