I don't agree for a minute that you can get "too used to tracers". Or that turning them off forces you to do anything but a whole lot of guessing, and then more guessing when the initial guess doesn't pan out, followed by more guessing when you miss again...
Thinking about this, I see your point. I'm having to re-evaluate my experience and how this relates. Since addressing your words directly would probably muddle the point, let me restate completely:
After thinking about it, I have to conclude it's purely psychological. When I originally had tracers on I thought to myself "Oh, if I miss this, I will get great feedback on where I missed whether high, low, forward or behind. Then I can adjust my aim and take a better shot next time." It's almost lazy thought, it also disengages me from using my instinct to pick my aim point.
Upon turning tracers off, I thought to myself "I can't afford to miss this. I have no feedback so I have to rely purely on instinct." As it turns out, relying purely on instinct was better.
No doubt I developed the instinct/feel for lead by flying with tracers on to begin with. No debate. Developing the feel without visual feedback can only be a long and frustrating process. If you remember, I wanted to get a precise visual representation of vertical bullet trajectory and you (I think it was you) showed me how in the 109 thread. Again, no debate that tracers are useful.
Once I learned the visual and developed my feel, turning tracers off forced me to engage the instinct. I regarded each firing situation as a "must hit" rather than an "experiment" (experiment as in let's fire a shot and see where it goes then adjust).
Purely personal, you may not have had this experience. This may even be completely unnecessary. It certainly isn't true that you MUST have tracers off to engage instinct.
So I guess I will no longer "advocate" tracers off but merely suggest it as something to try.
I don't understand your reference to tracers being an "artificial handicap".
You have my meaning backwards. I meant
no tracers as the "artificial handicap".
I hit on that tiny little burst most of the time. Would that improve if I stopped having a clue where my "misses" were going?
Is guessing going to help me improve (and I'd still like to improve, I won't be happy until my hit% is better than 50%, and I'm a long way from there...) more quickly than knowing?
Here's the thing - it doesn't matter whether you guess or know where your rounds are going because that feedback happens
after the fact.
Your initial aim point is only a guess anyways even if your skill at making guesses is so good that you "hit on that tiny little burst most of the time". Having tracers on cannot help you make a better guess "now", only in future situations.
Tracers can help you
learn gunnery but they cannot make you a better shooter during your burst except to tell you "I should keep on shooting because the enemy will fly through my stream" or "I should stop shooting because I'm clearly already missing".
Again it's purely psychological and personal, but turning tracers off made me turn off "learning mode" in my head and turn on "shooting mode". I used to waste time actually firing test bursts and then picking a new aim point (note this can still be useful in some situations, but not in the middle of a knife fight while you're trying to take a deflection shot).
Now that I've tasted "shooting mode" and have tried tracers on again, I can say that I am now in both "learning mode" and "shooting mode" at the same time. Once more, purely personal, others may start off in both "modes" at the same time.
To kind of answer your question (which is half meant to provoke a response and half actually curious), no. From what you've told me, you're a good enough shooter already that you clearly do not need to turn tracers off.
That advice is for guys like my past self who actually test their bullet paths while in the middle of a fight.
How much did shooting tracers off improve your gunnery? How accurate did it make you overall?
Ok, if you would like something scientific, I of course can't provide hard evidence for my my claims. I have not kept track.
Subjectively: could I be much better? Yes of course, my percentage is nowhere near "good". Did turning tracers off make me shoot better? Yes. Did turning tracers back on make me a worse shot? No. Will I continue to fly with tracers? Probably. Do I feel that briefly going no tracers made me "turn on" my instinct? Yes. Is going no tracers absolutely necessary to "turn on" that instinct? It probably isn't, but nonetheless it did work for me.
