Significant Weight loss at drying, but still no snap.

stem snap depends on size of stem. The only tricky part is that moisture evaporates off the surface of flower faster than it can traverse the plant material -- i.e. the interior has greater moisture than the surface. So, you just have to make sure it's actually dry after you seal it up to avoid major problems. if you seal it up and it gets soft (a sign of greater moisture) on the surface again, you need to take it out. If you control the temp/rh, you'll gain familiarity. The density of buds varies, so you'll never be able to exactly predict, but you should be damn good at it after a few harvests. Be systematic and learn faster. Take notes about temps/rh and duraction of drying you gave it and whether you had to pull it out of containers or not etc.. you'll learn how long it typically takes and avoid much of the hassle after that. Another way to know when it is at equilibrium with temp/rh is to weigh it. Have a representative bud of the typical size and density of your harvest and when it stops losing weight, you know it is at equilibrium with the temp/rh environment and is perfectly safe for long-term storage at that point. 2-way humidity packs give you room for error. They have a limit on how much moisture it can absorb or release, but gives you that buffer. Putting them in slightly early will correct itself. If drying temps and rh resulted in overly dry plant material, it'll provide moisture, too. 75-80% weight loss is normal.

I would check your humidity levels before curing, sometimes drying takes longer than 7 days and depending on how you dried it. If you just left it without wet trimming it’ll often take longer to dry then 7 days, or if you left all the branches in tact and just hung upside down as well. If using a herb rack it often drys faster. If using a tent vs cardboard boxes etc it’ll take longer case humidity levels and air circulation is better usually. Humidity levels for drying is typically 45% to 60% with temps needing to be around 60-70 f. For curing, Indica prefers 60-65 percent and sativa prefers 55-60 is what I found. There could be a possibility you have too much humidity or it just needs to dry longer. That loss of weight is normal and you will loose more, that shows it is not ready! Good rule of thumb is you will typically loose 70-80 percent of the weight after drying and an additional 2-5 percent curing.

Do not base it on snapping. In my experience, they end up too dry. Get a mini hygrometer and put it in the jar. Put bud in around day 7 of drying at 60% rh See what the hygrometer reads. It should go up pretty fast. I'll harvest and leave in the jar with lid off as long as it doesn't rise above 65% After a day or two In the jar, it'll stay around 60% and you can open jars for a bit until it drops back around 60% If you wait till they snap, then they're over dry and they sit around 55% and that's fine but you'll have to keep the jar completely closed for about a month until it rises back around 60%

Put a bud in a bag over night if its wet in the morning it needs more time drying.

hey 👋 in doubt, cure your harvest, and spread your buds out on a drying net for a day or two before putting them into jars with a Boveda pack 👍

Lota of videos on censortube to show you how it's done. You need to hear/see the snap on the video. Saw one where kyle kushman shows you exactly. Good luck.
