I think your reply has a somewhat familiar structure -- "it doesn't work for you because you used an [old / suboptimal / non-frontier] model. If you use X you'll see that it works". You might be completely correct! But these sorts of claims push the onus back onto the other person, without accepting any work for yourself. It gets tiresome to retest with the newest model every other week. Is there any data you can provide to support your claim, or any result you can contribute here?
