Almost always tight turns matter. The larger the track, the fewer the number of turns per lap, of course. The correction factor for the oversized tracks is essentially driven by the size of those tracks weighted implicitly by the athletics marks used in computing the correction, and that means about 300 meters. A couple of the sites account for a substantial number of the marks and an even higher proportion of quality marks, and they are 300 (SPIRE, Iowa State) or 307 meters (Washington), except Notre Dame (320).
What makes a bigger difference is that these facilities is that they have room and often spectator support that makes them better sites to hold big meets and these meets attract large groups of quality competitors. It would be the height of idiocy not to use these facilities for qualification purposes; probably the stupidest idea that I can think of being proposed, and that takes some doing. The Big Ten has been using the SPIRE facility for the Big Ten meet the last three or four years and the people involved that I have talked with really like it. First, it allows the mens and womens meets to be held at the same time rather than at two different sites. Second, there is room for fans and the track quality is good and the support for field events is better than at most (almost all) indoor facilities. Of course, the quality of the top 200m banked tracks is similar (e.g., Texas A&M, Arkansas).
