It was a tenuous link at best. I was merely noting that the J15 (as a class 1P2F) may not be as suitable for a fully laden 7/8 coach train on a busy gala day at a 'top' preserved line than a larger, more powerful locomotive (the size of which I did not specify, in this case it doesn't have to represent a Pacific-sized loco, and could be something as small as a class 2 or 3), and thus wouldn't be able to take as many fare paying passengers, and so the railway would not be able to develop as big a profit margin over the costs of getting the loco there. That's not 'big chufferitis'. That's simple physics and economics. Your decision to interpret it as big chufferitis and mention so gives the impression that you are looking for any opportunity to bring it up. Again, that's something that can get rather irritating after only a very short space of time.
