All opinions are welcome but opinions are not facts and don't make good arguments.

It compresses about .04 Mach too slow and nothing else in the game compresses at all.

You obviously never fly any 109's, 110's, or A6M's.

Just me, or do those streams seem to cross in the 150 convergence just above the hill....

You are picking yourself a fight that you won't win, and looks like you are probably going to birdog Hitech any chance you get to rub his face in a none event thing. 15 years of interacting with him in these forums, I can tell you he won't put up with it. Those rounds cross inside of a 2ft circle at convergence IP with a dispersion cone that still describes the hose out to 650 and the 4Mil dispersion area. Is there any real reason you are starting down this rabbit hole other than your own vanity?

And please tell Hitech your answer directly since you have taken the opening shot at him.

Sorry buster...was told "show the facts effect changes".

If they programmed the nose guns to converge in a 38, then they programmed it wrong.

How did I take an opening shot at Hitech? And why do you feel obligated to take up for him?

And to be perfectly clear...if posting substantiating data to support a bug claim is picking a fight.....well then close the forums down.

And really...VANITY bustr? What the hell does vanity have to do with pointing out the streams cross in a nose mounted gun platform?   

You old timers need to give it a rest when it comes to suppressing inputs from new players.

Dobs did you even look my screen shots? Dispersion at 1000 yards will make the bullets very by about 10 feet. Any convergence settings will be a difference of 6 inches or less.

I did Hitech....it just seems to me if bullets are converging the point at which they converge will have a narrower cone then at a 1000' yards.

Maybe its the visual part of it with the smoke trails throwing me off..but I snipe at d800-1000 quite a bit...especially on a zooming bandit. 

But thank you for the reply...if you say its only 6" difference at 1000' yards between 150 convergence and 650 convergence then consider the matter dropped.

The nose guns are mounted so close together on the 38 the difference in that dispersion cone between those range distances wouldn't be that much different. Just trying to visualize it. Now think of the difference between the same range distances on say a Jug. That cone would be markedly different as the sets of guns are many feet apart. A much greater angle to start with. FWIW I usually have mine set all the way out. Doesn't help much as have a sterling rep of not being able to hit the broad side of a barn. Maybe in the next 10 years I'll pick it up!

You may have misinterpreted the advice given. Flight model changes require data but supplying evidence that something in the game isn't like real life doesn't mean it will get changed. For example the convergence on the P-38 is not true to life, as you pointed out. However the change you request would not be noticeable unless you could turn dispersion off, so it's not worth coding the change, which HiTech already explained, and I already explained, but maybe you missed that.

Well, if we ignore dispersion for a moment, taking a worst-case scenario of 150 yards convergence, at 300 yards the bullets would be spread back to 19 inches, correct?  Then for every 150 yards out it would widen by another 19 inches.

So going over a space of 850 yards from convergence, I get 5 2/3 * 19 inches, so 107 inches.  Or about 9 feet.

So it's not negligible if you consider the worst case we can give it in game.  Myself, I set it to 650 and go on about my day because at that convergence setting its effect is practically irrelevant compared to dispersion.

That's correct Wiley, and you would add the 20 ft or whatever of dispersion plus aircraft movement to that 9 ft at 650 yards. Assuming you don't mind reduced density of fire.

But when you compare setting guns at 650 to setting guns parallel then the difference is negligible.

The only reason to ask for the motor cannon to be corrected is that you can set the cannon to shoot unnaturally high when it was physically impossible in real life. Rough weather, bad landings and a maintenance boo boo can cause one or more of the gun mountings to wander and duplicate what Hitech purpose set in his program. But that is still within reality because your barrels are ganged inside of a 20x6 inch area. By 1945 P38 guns were harmonized to 2000ft(666yds). The motor cannons are not within any margin of reality.

Here 1945 AAF Manual 200-1.
