The standard deflection test is well documented and well known, Dr Dave vids etc… As I said, I’ve done it numerous times with a wide variety of non LD and LD cues/shafts and get pretty consistent results. Its generally recommended to do it at high speed, but I do it with same general outcome at any speed. I do see very minor differences but its barely discernable, under 1/2” on the full table length high speed test shot, and 95% of the time I’m nailing the center diamond square, even with heavily applied max side spin.It's a simple deflection test, put a cueball on the spot, put an object ball middle of the opposite rail, aim center to center, then shift the whole cue fully to one side or the other, don't use any pivoting front or back as that changes how the spin works due to curve too much, just shift the full cue and bridge to the left or right edge, aim straight at the ball on the far end of the table. When I do this, house cues and some other cues fully miss the object ball, what I consider LD shafts hit the ball 1/3 full or better.
If the results you are getting are that close, you are compensating for the spin yourself and not testing the shaft and only the shaft. The reason people see different results is they do the test at different speeds, putting spin on the ball in different ways, maybe testing with the balls closer together, compensating for spin subconsciously when aiming, whatever. The important part is to make sure you are testing only what the shaft does, not what your aim does.
If we all follow the scientific method, the results will be the same, there is simply no other way for them to happen. Same test, same result. If not, then the test is flawed, or the basic final idea we are trying to test is flawed. Since we the idea of deflection is now very well known, there is no issues with the actual idea/theory, that leaves how we do the test as the variable if people see one thing and others see another thing.
I’m not arguing that deflection isn’t a real thing, quite the opposite. Nor am I arguing that I’m not doing something unconsciously in my visualization/aiming/bridge/stroke to compensate, as its the only possible explanation.
I doubt I’m that unique, and suspect that there are plenty of folks that do similar, as there are clearly many folks who report they just pick up any cue, hit a few balls to get a feel for it and play the game at a high level. For these types, the “LD ness” of a shaft just appears to not be that important of an issue. Road players used to consider the ability to play off the rack to be a fundamental skill.
I personally think it relates to how one applies spin, in terms FHE, BHE, parallel etc, bridge lengths, and pivot points. There are myriads of accomplished players who have no real concept of these terms or concepts. They probably just have a good intuitive feel for the shafts pivot point and apply spin via BHE whether they realize it or not, as the offset angle is simply incorporated into their visualization, stance, approach and stroke. Personally, when I heard first these terms, and started paying attention to how I hit the ball with side spin while keeping these perspectives in mind - I felt like I was applying perfectly parallel side spin. When a smart seasoned pool player friend watched me and when I saw some video of my self I realized that I’m actually minorily angling the cue with my rear grip hand, ie a form BHE. Also, over time I’ve realized that I do subconsciously use different bridge lengths when using different cues & shafts, which I guess implies that I’m intuitively adjusting my bridge/stroke to optimize the pivot point/BHE ratio…? I suspect that very few folks actually use strictly parallel english, but rather a dynamic combo of FHE/BHE that is just incorporated into their game. Again, I had no idea that these terms/concepts even existed until I started playing pool again after decades away and catching up on all the modern terms & educational content that is now available.
Its taken a lot of thought and time to realize this stuff for me, and I still really can’t say what exactly is going on. This also means that whatever I’m doing is not really teachable or marketable, and thus it makes good sense for instructors and equipment makers to advocate lower deflection cues as a general practice. I myself prefer and play with moderately low deflection shafts (Cynergy CF 12.5, for me similar to the good old 314 as a baseline ref)…
Anyway, I think the take away for this thread topic is that IMO how much time it takes to adjust to a LD cue depends on many personal factors which are nearly impossible to characterize.
Personally, I don’t know why anyone who already has a strong game and who is also sensitive enough to a shaft’s deflection characteristics such that they are finding it difficult or time consuming to adjust to a new shaft - why bother? There are plenty of both wood & CF shafts with wide ranges of deflection characteristics, such that any combo of shaft features can be found to suit one’s preferences…
An analogy; most players tend to have a preference on a cues balance point, rear or forward balanced. Same with cue length; 58 vs 59 vs 60”, 29 vs 30” shaft, equal split or not, etc. No “correct” answer, seems to depend on ones personal anatomy, stance, playing style, etc. Over time I’ve found thru trial & error that I prefer standard 58” cues that are rearward balanced. I can and do play with anything, but I’ve settled on what I like and even though I’m a cue slut, I prefer to stay with cues of those specs. Ie I don’t continue trying to play with 60” cues or heavy forward balanced shafts under the assumption that they will help my game if I just get used to them, because others love them.
Anyway, those are my $0.00002. As REM said, “Oh no I've said too much, I haven't said enough”…

Cheers
