Well Known Nuisance
Some engineers are very clever and others have experience that they can also rely on. One can set the gas on an AR so that with the perfect weighted buffer it will give the most manageable felt recoil. Works well on the range. In the world of real life having more gas than is needed is what the experienced engineer will consider for when things are not optimal like with fouling, dirt, and with less than optimal ammo.
Several of my AR uppers came over gassed; that is normal for economy uppers. That is done to ensure function if something is not optimum. I Simply upped the buffer wt and they function fine with any brand of mag and the ejection is to behind and not forward. A down side is that the BCG components might wear or fail sooner. But such parts are cheap and I keep spare parts.
The more gas, the more rapid the BCG speed. The more rapid the BCG speed, the more to the right front will be the ejection pattern. A faster moving bolt will be extracting while chamber pressure is higher. Means more wear on the extractor for example. Everything should be adjusted from what I have read to eject from 3-4:30.

Yep, and with no deflector/bullet bump it does the same thing. What???
