Given what I got out of his post, i'd say you applied it correctly. If you lose you'll have 2100 which is still good for your table and blinds. If you win you'll have ~3200 which puts you in the position to still lose an all in to the next big stack and still have 800 chips which is not great but not terrible. Given that most of the table is medium stacked you will be able to push them around more easily than short stacks and big stacks (mentioned in Harrington 2). I think its a decent call given the table. Still need to take into consideration your previous table image and how this call will alter it for future hands.
