Original Text

(...)

   The Rank computation is described in Section 4.1 of [RFC6552].  A
   node's Rank (see Figure 4 for an example) is computed by the
   following equations:

      R(N) = R(P) + rank_increment

      rank_increment = (Rf*Sp + Sr) * MinHopRankIncrease

(...)

   This section illustrates the use of OF0 (see Figure 4).  We have:

      rank_increment = ((3*numTx/numTxAck)-2)*minHopRankIncrease = 512

Notes
-----
s/rank_increment/rank_increase/

It'd be better to use "rank_increase" as the variable name for consistency, 
which is used in Section 4.1 of RFC 6552 
(https://tools.ietf.org/html/rfc6552#section-4.1):

[excerpt from RFC 6552]

   The step_of_rank Sp that is computed for that link is multiplied by
   the rank_factor Rf and then possibly stretched by a term Sr that is
   less than or equal to the configured stretch_of_rank.  The resulting
   rank_increase is added to the Rank of preferred parent R(P) to obtain
   that of this node R(N):

   R(N) = R(P) + rank_increase where:

   rank_increase = (Rf*Sp + Sr) * MinHopRankIncrease
