The guy was asking for previous experiences, I don't see the need to sound hostile.
Who is sounding hostile, apart from you, perhaps? Just questioning the approach.
This poster obviously had received on-topic advice from a consultant. Apparently, less than complete trust was accorded to that advice. In a case like that, I consider it behooves one to be forthcoming and to state at the outset that certain advice has been received from a consultant and the poster desires to test that advice here on the forum. Instead, in this case, the OP said nothing about advice already received, presumably from a professional, then he asked how the matter should be handled. Then, when confronted with an answer apparently not liked, he comes back with a retort saying, in effect "Well, so you think, but I have been advised otherwise." It comes across as less than gracious.
