True, but no two humans are alike either.
Forums tend to have dynamics that are constantly shifting.
After a topic has been opened up and input has been added, simply adding more to it from some posters would tend to dilute it and potentially steer it off topic which in turn would be a nightmare for someone searching the archives for a specific topic.
Someone once asked me in our chatroom why some of us talked about boring everyday stuff in it.
My reply was that many could care less to hear about flame front propagation in various combustion chamber configurations and their effect on complete burn cycles in an internal combustion gasoline fueled engine and the cylinder wall wear involved when a piston is shoved off-center to it's bore as a result of a weak at best design. Too much offset equals a geometric loss of efficiency due to poor connecting rod angular geometry with a greater instance of wear on the piston skirt and cylinder walls. Not enough will defeat the purpose of even having an offset pin while at the same time will give it a greater power advantage over the further offset pin.
Hemispherical combustion chamber cylinder heads push directly down on a piston eliminating the need for an offset wristpin location which in turn alters the geometry to the point where the piston just floats down the bore with less friction than the piston in a wedge-type configuration.
Loads of power with a disadvantage of piston slap as the piston and bore start to wear.
The wedge style engines don't have that disadvantage but at the same time suffer parasitic friction losses which in turn reduce final power output.
Were you aware that the 500 cubic inch displacement 11,000 plus horsepower hemi engines in a topfuel dragster are actually based on the physical dimensions of the cylinder block of the original Chrysler 426 street hemi?
Heck, it takes more parasitic horsepower loss to run the Roots style supercharger on one than the street hemi can produce to put it into perspective.
Really interesting stuff when you start to dig into it, if you are into it.

While very interesting to me, most would have walked away from my monolog long before I got to the end, and actually that is only the beginning.
It's more of a need to know only if you need to know it kind of topic.
Were you aware that offsetting the crankshaft centerline to the cylinder bore centerlines on an inline four cylinder engine will actually increase the power cycle duration?
The only problem with that configuration is the loss of the dynamic balance that in the end would only serve to tear the rotating assembly to shreds.
I'm sure if someone took the time to work out the math on a dynamically tuned balance shaft it could be a winner, but for now, manufacturing will likely only stick to a tried and true formula.
What makes an inline six cylinder engine superior to a four is that the rotating mass balance and the dynamic balances have a way of cancelling each other out because of how the power pulses are spread out over the 4 cycles that are involved.
I think that says about enough to see where topic drift could be a problem, plus who actually wants to read a wall of text?
Or, picture a sales catalog without any order to the index, which in the end might prove to be useless to most.
