I think that's kind of a ridiculous assumption, but it's also somewhat moot as none of these decisions should necessarily be based upon "realism" as much as they should be conducive to good gameplay.
An excellent point, but as implemented it would suggest that all mechs carry magical targeting computers which are able to instantaneously and perfectly make such targeting calculations.
In the lore, which I personally do not really care about, it mentions exactly such
targeting computers. Various mechs had more advanced targeting computers, which enabled them to function more accurately. This would imply that without those advanced components, most mechs firing is not in fact perfectly accurate. The targeting computers take up critical space and tonnage based upon the weapons systems they are linked to, and reduce things like recoil for those weapons, account for atmospheric conditions, weapon drift, etc.
Again, I would tend not to use this aspect of battletech to implement just widespread randomness across the board in relation to gunnery, but I think that it's worth noting when considering the type of argument you presented there, which attempts to argue that mechs are somehow capable of magically always landing shots in an exact location.
Your confusing precision and accuracy. Precision is the consistency with which a ballistic weapon, laser, PPC, etc is able to hit a fixed target. Accuracy is the ability of the pilot to aim said weapon. Ballistic weapons have since the dawn of their creation followed some very basic principles. A given projectile fired at a given speed and aimed at a given elevation is going to travel a given distance. Change none of these factors and subsequent projectiles will have the exact same behavior.
Mechs are highly precise weapons platforms. If aimed at a fixed point and mounted in a fixed location, an AC20 should hit the same spot at a given range every single time with such little deviation as to be statistically insignificant. Most pilots are neither accurate nor precise. No one here can claim that they hit the cockpit of their target dead center every single time.
If you wish, I can theory craft the process for you thusly:
You aim your reticle at a target 1000m away for a long range alpha strike. The computer actively monitors what range you are aiming at as represented by the range indicator on your hud. As this range changes, the computer looks up the ballistics properties for each weapon and then adjusts their convergence. It's not hard to imagine that a small servo is part of the mount to accomplish this. Obviously at extreme close range, they should not converge, but the difference between the convergence angle at 100meters and at 1000meters is relatively small and completely dependent on how far off the center aiming point the weapon is located. So the weapons move ever so slightly to adjust convergence, and then fire. This is supported in the books (which I'm currently reading by the way) in that even the industrial mechs modded for battle still have very simple targetting computers.
So your basic bottom line targetting computer can be programmed with the ballistic tables of weaponry. It is not however capable of locking a target, tracking a target, or predicting the amount of aiming required to lead the targets. These basically give you the crosshairs, monitor range, and rely on the pilot to do all the aiming and movement prediction.
The next level of targetting allows the pilot to lock a target, but otherwise is unable to provide movement prediction. It is capable of the LRM's and SSRM's since these are guided weapons. This is the one we have on all mechs currently. The pilot is till tasked with movement prediction and physically aiming the non guided weapons.
The next level up, you have locking and movement prediction in that once you lock a target, the computer gives you a reticle which tracks and displays how much you need to lead the target in order to hit it. This is the classic jet fighter hud everyone knows when "switching to guns". Up to this point, the calculations are instantaneous and the pilot is still actively aiming all weapons with the computers doing very simple background calculations.
The next level up, the computer takes over active aiming abilities and applies extensive calculations. The pilot merely designates the intended target and the computer actively tracks the target with motion prediction and provides a final shooting solution when the pilot hits the fire button. These would be floating point calculations and are often described in the books as "the pilot waited for the target indicator to green up with a solid lock and fired". Still, the pilot can manually adjust the aiming point at any time and fire without having a solid lock. I believe these would be yellow indicators.
Finally, the top of the line targeting computer does all the above but goes one step further and does it for multiple targets allowing the pilot to both target multiple enemies and designate which weapons to fire on them simultaneously
There is no magic involved and all the above is consistent with lore.
It's not hard to imagine that an technical and industrial advanced civilzation capable of producing fusion core reactors and giant stompy robots with Gauss, PPC, and lasers could equip those weapons in such a manner that they could be adjusted on the fly for various different convergence ranges. Arms are a given, but a small servo on a torso weapons mount could also do so.
Don't make me bring real math into it.
