I used RTK as well, except with the website kanji.koohii.com instead of Anki, to learn 50 kanji a day. Did that for 2 months before moving to Japan, started using Anki for vocab / grammar, and passed the JLPT 1 examination in less than a year and a half.
My senseis and American coworkers were, but knowing the meaning of individual kanji is still two steps away from learning the actual reading and usage in compound words （熟語）, so I still had no right to show off.
