My point is that if he sets his weight so that the BC needs to be dead empty in order for him to hold his stop there will be times when that won't be enough to let him do so.

I recognized that. He's a newer diver and once they figure out how to fully dump via "contortion" they end up doing it with ease. You and I both agree on that.He's saying that if a diver took my suggestions to twist and turn to squeeze every drop of air out of the BCD during the test, then the diver would have to do it on every subsequent dive since that is what the weight is adjusted for.
Once he finds the actual weight needed to stay down with an empty BC then he can adjust for what ifs. I dive with a few extra pounds because I like to keep extra air in my drysuit for warmth. We all have our own variations, but being grossly overweight shouldn't be one.My point is that if he sets his weight so that the BC needs to be dead empty in order for him to hold his stop there will be times when that isn't enough to let him do so.
I’m a new OW diver trying to figure out optimal weighting and buoyancy. I am 6 feet tall, 245 pounds with around 15% body fat. I’m diving in salt water with a Neotek2 8/7/6.
There are lots of dive clubs in our area. Marker Buoy, Kelp Crawlers, Bubbles and Suds, Thursday Night Divers, etc. Most can be found on bookface. There is also NW Dive Club linked below. You're in a area with a huge diver presence and some of the best diving in the world. It's 6-gill season right now so you have that to look forward to.I appreciate the discussion and perspectives. What I am reading is that I should be able to reduce my lead a little now. I am also reading that I should be testing various weighting using the floating method at the surface to test where I should be weighted more often.
Once again, the feedback and discussion helps me understands everyone's perspectives and experiences that got them there.
I’ve used several calculators and methods to figure out weighting; they vary from 24-27 pounds. Based on the data I have experienced while diving, it seems like I need another three or so pounds and larger single tank wing than 32#. Thoughts or recommendations?

Some things aren't adding up for me here. I saw some posts on doing a proper weight check, and I would recommend this as well. Just going to add a few points.I’m a new OW diver trying to figure out optimal weighting and buoyancy. I am 6 feet tall, 245 pounds with around 15% body fat.

I bought a 32# wing which doesn’t seem to lift me out of the water enough for a surface swim without a snorkel or using my air. With that said, towards the end of my dive, I can’t seem to stay down with an empty BC and 27 pounds of weight with a steel 100.
Thank you for your contribution.Some things aren't adding up for me here. I saw some posts on doing a proper weight check, and I would recommend this as well. Just going to add a few points.
27 lbs with a steel 100 sounds really high to me. However, you are also using a much thicker wetsuit than I'm familiar with, so it's possible that's what you need. For the sake of discussion, your lift needs to be sufficient to offset your total ballast. I'm assuming that you are able to at least establish neutral buoyancy at depth. If that's the case, that's a data point indicating that your lift is not undersized. That said, with the amount of weight and the negative properties of the steel, you may be really close. Your exposure suit offsets some of the weight at the surface, but that goes away at depth with a wetsuit. How full is the wing when you first get to the bottom and establish neutral. If it's full, or nearly so, you may need a larger wing for that given weight.
Since you said wing, I'm assuming BP/W or at least rear-inflate. No matter how large the wing is, it will never be able to float someone during a surface swim without using a snorkel or regulator. Assuming we aren't talking about backstroke, the lift is all on the diver's back, so at most the back will be at the surface, but everything else underwater.
You really need to do a weight check at the end of your dive during a safety stop. At this point, your tank is closer to empty, your wetsuit has re-expanded. So in other words, you'll be at your most buoyant at this point. Your wing should be empty, or nearly empty. If it's not, there's some weight that can be shed.
If your dive count in your profile is correct, being overweighted is pretty much expected. A lot of instructors teach with their students overweighted as they feel it's easier that way. Also, it's a normal tendency for a newer diver to hold a bit more air in their lungs. This will get better with time.
Perfect. Sounds like then you are probably as close on weighting as you need to be. 27lbs of lead and a steel tank will be pretty close to the wing lift capacity. Especially if that 27lbs is on top of the backplate itself. Larger wing definitely sounds like a good idea then.Thank you for your contribution.
Yes, neutral buoyancy at depth is no problem. Once I drop weight and get down to depth, I give my BC no more than 2-4 quick air shots and I'm good. The rest is breath control and my lungs. Yes, it is a BP/W setup.
To add additional clarity, I was talking about backstroke on the surface. The 32# did not do well getting me out of the water, but my WTX-D40 is sufficient to accomplish out of the water backstroke surface swimming.
At safety stops, my wing is empty or pretty close to it.
