The speed of the groove underneath the stylus does not change stylus/groove friction. You can easily prove this by placing your stylus on a blank, grooveless vinyl record and adjusting antiskating so the tonearm does not drift inward or outward. Then switch speeds from 33 to 45 and observe the tonearm remains stationary. This is because stylus/groove friction remains constant regardless of the speed of the vinyl underneath the stylus.
Furthermore, as Bry correctly states, the speed of the groove varies by less than a factor of 2.5X. The speed of the vinyl groove is directly proportional to the groove radius. An outermost groove radius is 146-mm whereas an innermost groove radius is 60-mm. The speed of the groove past the stylus changes by a factor of 146 / 60 = 2.43X.
