Your math is correct. The table for AS "value at 18" is off by 0.004 or 0.005 for some reason. Here's a correct list of attack speeds at level 18: http://leagueoflegends.wikia.com/wiki/List_of_champions/Statistics_at_level_18. One thing to note though is that the wikia lists Rakan's AS growth as 3% now (changed from 1.9% to 3%), so your calculations might have became outdated.
