I removed the word from my version.

I tweaked the words ever-so-slightly to be even more specific:

        (b) FT observations SHOULD be taken and incorporated into the
            RTO at least once per RTT or as frequently as data is
            exchanged in cases where that happens less frequently than
            once per RTT.

The supporting (non-normative) text that followed is still there.

Seem OK?
