Sorry, i found this a tad confusing .......so this clarifies the situation in that 197 points is equivalent to pick 56 ......so it's 20% discount or 197 points, whichever is greater
From the rules the bolded bit is the most important
If He nominates the Crows and nobody bids on him before pick 56 we can use pick 86 for him
"The listng of F/S players and local Academy graduates is facilitated in later rounds because the discount rises steadily from 20% in Round 1 to 100% at pick 56 (if a player is bid from this point, a Nominaing Club need only use their last pick in the draft to list the player)."
