This issue has been beaten to death. I did post a one liner of semantics issues. I don't get involved in debates on the forum, so will give the OP my opinion, then back out. I have stated before, have not brought a dog along as a hunt test dog, but, have run field trial trained dogs in hunt tests since the 1980's. In the past 7 or 8 years started judging hunt tests at the Master level plus a few seniors and juniors. What I have noticed, hunt test dogs can't compete at the field trial level, even though nice dogs, because the bottom has been taken out of them at a early age. By the time they are three years old, Master level or HRCH level dogs for the most part start to break down on marks many times at about 100 to 150 yards. I have trained with a number of these dogs, who might have been trial dogs be completely put in hunting modes by constant handling, cookie cutter tests, and general breakdowns. Handling is encouraged to get their passes and it is very hacky at best. Moving on, "bottom" is mostly a field trial term that dogs with great bottom have the ability to run 200, 300, 400 yards plus with swims of the same length. Conditioning to these great lengths is done and the lack of bottom dogs are quickly discovered. Now enter marking , many young dogs have a sacacity from the line to break through cover,carry natural straight lines to a point and look like they have great bottom, but, mostly are very good marking dogs with a lot of "drive" or "speed" or "style", will they have the hunt test vernacular of "perserverance" later on who knows, that's the hunt test word for bottom. Do they need the "bottom" for hunt tests venues, me thinks not, do you want to keep the bottom for these same Master or HRCH dogs if you choose to make them QAA dogs, absolutely . So that's my two cents on bottom and to quote a Forest Gumpism, that's all I have to say on the subject.
