Please note that the friction measuring device related to the table i 1959 is the Tapley meter.
The Tapley meter are also related to your first table. (minor differences).
From ICAO Study Group on Snow, Slush, Ice and Water on Aerodromes there exist a letter dated 27th October 1967, from UK related to:

Tapley - or spot measurement decelerometer speed 25-30 mph and figures as follows:

• Good 0.6 and above
• Medium Good 0.59 - 0.51
• Medium 0.5 - 0-4
• Medium Poor 0.39 - 0.3
• Poor 0.30 and below

Both tables can not be right.
