Here are a couple hacks for you with trimming. And let me preface this with this one thought.....I HATE TRIMMING!
I like to start plucking big fans a couple days before harvest time. I find its easier to pluck (grab the bud carefully quickly pull the fan leaf downwards) the fan leaves and can generally take them off 3 to 4 times faster than I can with scissors. Doing this a day or two before trim makes trim day much easier and allows me to allocate my time as my back sees fit instead of doing it one shot. You can even go so far as spreading a trim out over a couple days if you have any sort of chronic pain associated with trimming.
I wash my buds so I only do a rough trim at best before the wash. I hang them to dry for 2-3 days and then I do my final trim (I don't cut off all the sugar leaves...they have lots of trichomes on them and just wrap around the buds and protect them) and cut the buds off the branches and into paper bags for 2 weeks of drying via the slow and low method in the fridge. I put about 40 grams per paper baggie and gently shake them every couple days. By keeping the amounts about that same 40 gram mark, it lets me do a quick weight by hand and I have a pretty good idea of when its ready to go into jars.
I find that i usually jar them up with the RH about 67% and slowly burp my way down to the 60% range that I like. Since I am the primary one smoking the buds, I don't need to waste a ton of time trimming something. My friends know the quality of the buds, so they don't mind a few sugar leaves on the buds if they pick some up.
Thats just my way. I hate trimming and try to do as little as possible with the scissors. If I can't get the stem of the leaf with the scissors or if I can't pluck it off, it doesn't generally get cut (unless is a very leafy strain). If you ask 10 growers how to trim, you will likely get 10 different answers as to how to do it. My advice is experiment with it. I find less use of scissors gives me less of the hay smell. I like my terpenes. Find what works best for you.
There are some growers that will cut a plant whole and hang it upside down whole and dry it for two weeks, knock off all the dry leaves, cut the buds off the stem and jar it up. Doesn't get much more simple than that. Other growers have OCD and trim the freaking hell out of all the buds. Find your niche....there is no right or wrong, just right or wrong for you.
