The only problem is that IRL aircraft killing tanks with a gun Including the IL2 were very rare.
By far more tanks were killed by bombs ..or other tanks then by gunfire..even from the IL2.
If this were the case. there would be little to no reason for a country to have tanks.Or aircraft with bombs Just build aircraft with powerful enough guns to kill tanks on a single pass
The difference isnt that the IL2 here is over modeled. Or that the gun is over modeled. They probably aren't.
In fact. against medium tanks such as the panzer. Its probably slightly under modeled.
But...
The difference is that IRL pilots couldnt just switch to microscope view so they could hit an area with pinpoint accuracy 4-5 feet square while traveling at over 100 miles per hour. not to mention that its guns possessed such a recoil that it made accuracy beyond the first round or two of a burst very difficult at best.
While here. such ill effects are minimal
"The worsening of flight characteristics of the new Shturmovik, as with the IL-2 with the ShFK-37, was due to a large mass/wing ratio and the design of the cannon pods which lowered the aerodynamic performance of the aircraft. From an overall point of view, the IL-2 had poor balance; this indefinitely lowered cannon accuracy. This major factor was amplified by the strong recoil of the cannons during firing. According to NII VA VVS KA data (a letter of NII AV General-Major M.V. Gurevich, from 19.11.1943, to S.V. Ilyushin), the maximum strength of the recoil , present for .03 seconds, on a ground-based platform(existing technology of that time didn't allow the measuring of "the strength of recoil" in aircraft and much less in the air during firing) consisted of a considerable amount - 5500 kg, with a recoil average of 2500 kg. All of this contributed to the wide dispersal of shells during aerial firing."
Results based on the proving grounds trials showed that the well-trained Shturmovik-pilot in all normal circumstances of attack, could attack from a 30 degree angle at a distance of 300-400m - waging fire that would assure the destruction of the Pz.IVG medium tank at .04 to .07. For a halftrack such as the Sd Kfz 251, no higher than .08 - .17. In other words, for the destruction of a solitary tank, vehicle etc... it was necessary to attack with about 15 armored IL's"

He's just gaming the game a bit
