I read your post perfectly well. Again, what you are talking about is not field artillery. The German 88mm and the US 90mm were direct fire weapons. That you took the 4:1 shot ratio from a poem and started talking about tanks and armor penetration was rather telling that you were still misunderstanding the point.
And speaking of not having read posts carefully, you will note that I have said “meaningful indirect fire” every single time, not simply “indirect fire”. Any gun can be used for indirect fire; rifles and pistols are capable of and can be used for indirect fire. Tanks can and have been used as bastard artillery by elevating the main gun as much as possible and positioning them on a reverse slope. If you look hard enough you can find old field manual instructions on using volleys of rifle fire into the air as indirect fire. These aren’t particularly effective methods of producing indirect fire as the weapons weren’t designed with indirect fire in mind. Hence my use of the word “meaningful”.
Then you might want to produce some evidence and understand why the virtues of the 88 are irrelevant to the post you responded to. If I can quote your own cite:
