Plain wrong statement: "45 presenting the cartridge with the problem of tracking a groove which makes the stylus accelerate at a greater rate"
This greater acceleration does not exist. And more energy is NOT being put into the system or the volume would be louder on a 45!
This poster is confusion lateral and vertical groove velocity with linear groove velocity.
In reality, for the same lateral or vertical velocity (the signal-generating directions) the angles on the groove are more gentle, as the same displacement of the stylus in the vertical and lateral directions happen over a greater (linear) length of the record groove.
