According to the manpage "The idle3 timer is set in 0.1s for the
1-128 range, and in 30s for the 129-255 range."
So 148-128=20... 20*30sec = 600sec = 10mins, confirmed with:

    ~$ sudo idle3ctl -g103 /dev/sda
    Idle3 timer set to 600.0s (0x94)

It's most out of character for me too, but I don't have access to a
DOS environment to run the official wdidle3.exe .
