I stand corrected, I knew that it was some obscure ratio and 13.5 was the
first number that popped into my head. The following is taken from
MS Documentation which indicates that Windows is less accurate at
timing.

PS: 55 msec => 18.2 ticks/sec, Win95 is MS-Dos in disguise.

=====================================================
Remarks
The following table describes the resolution of the system timer. 

System Resolution 
Windows NT 3.5 and later The system timer runs at approximately 10ms. 
Windows NT 3.1 The system timer runs at approximately 16ms. 
Windows 95 and later The system timer runs at approximately 55ms.
