6.2.  Monotonicity and Counters - Fixed-Length Dedicated Counter Length

Current Text:

General guidance is that the counter SHOULD be at least 12 bits but no longer than 40 bits.

Proposed Text:

General guidance is that the counter SHOULD be at least 12 bits but no longer than 42 bits.

Other Supporting information below:

This is a suggestion to increase the maximum counter bit-length from 40 to 42. This leaves 32 bits left for entropy, which is perfect 32-bit random number generators. (128-6-48-42 = 32). The number 40 made sense in version 7E (128-8-48-40 = 32).
