990V is a case where the reference route is signedbetter than several TOURING routes in the state. Not only is it fully signed from NY 30, it is signed at regular intervals along the route, along with signs at major intersecting roads. Unlike any other reference route, the legal name of the road is "Route 990V". I'm going to get some major pushback for this, but I'd argue that NY 990V belongs in the system solely because NYSDOT basically considers it equivalent to a touring route. The number of sign replacements the thing has gone through show that it's not a little fluke that the thing is signed. There have been no fewer than 2 total sign replacements along that road that replaced the shields. It's not a case like the other three where shields are infrequent or (in the case of 962J) mostly removed.
Back on the initial topic, NY 71, 124, and 344 are cases where you have long wyes with two legs signed as the main route. For each, only one is actually the touring route. This is really a Region 8 peculiarity. I say either include the other legs of 71/124 or take out 344.
