Hey RACK authors,

we're evaluating the nuts and bolts of RACK in its current version and 
we are missing variable explanations.
Most of the variables are listed and explained in section 5 (Definitions 
of variables) but at least two are missing.

SND.UNA
RACK.dupthresh << This is where we're stuck

And I think this paragraph from section 5 needs two cosmetic newlines:
"RACK.reo_wnd_persist" is the number of loss recoveries before
resetting RACK.reo_wnd "RACK.dsack" indicates if a DSACK option has
been received since last RACK.reo_wnd change "RACK.pkts_sacked"
returns the total number of packets selectively acknowledged in the
SACK scoreboard.

Best regards
Felix Weinrank
