Upon closer inspection...
"Note that throwing speed is
typically not applied to combat speed, but only treated as attack speed, as it is usually considered a feat of strength more so than a measure of how fast the character can run or fight"
I think
typically is the key here - the notation is not a blanket statement. For example, Tanktop Master clearly puts
all his strength into
throwing a building. Using common sense, he most likely cannot achieve the speed of the thrown building, either casually or consistently. Boros's knee launch is basically a two-part regular kick. A normal kick would generate far more force through basic biomechanics than somebody putting their knee into you then swinging their foot upward.
We also need to remember two key details. 1 - MB loses power as its duration increases. The first punch melted the ship. No other attack replicated this. Not even that puny crater Boros made with Saitama's body on the Moon. 2 - The kick was the only upward attack. Saitama could only counter this if he could fly down. None of Boros's other attacks after the kick budged Saitama at all.
So I disagree with the last one.
As far as the supersonic feat, the context of the feat is clearly different from what TTM did. That was a casual blow that generated that much air pressure as a result. The force and speed of the resulting pressure has a direct relationship with the last timeframe of the hammer swing that imparted the force. I don't think the speed of the air would be faster than the source of the air unless he had some weird hax ability that caused his attacks to gain energy over time and not lose energy over time.
So I disagree here too.
I still disagree with the PS, FF and "Saitama's Reactions" sidebar too
