We count 288 comments. Most of the errors were from subthreads under your own toplevel, where only x comments are present from the link (which is fine), but you counted x+1.

If it makes things easier, all threads under the same toplevel can be submitted as one proof, provided all those threads are finished. For example, this toplevel was submitted & approved for 41 comments total: 40 comments in all subthreads combined, +1 for the toplevel itself. (Note that we do not count journal entries, such as network or catch-all posts, in the comment total.)

Everything else checks out! Your total is 288 shards in the bank.
