Multiple runways doesn't have to equal poor training.
True, but currency is so important with crosswinds. During my PPL I went through a phase of the wind often being near the 17k demo for the plane (at a single runway airfield) and soon became an expert at crosswind landings...then after my PPL I went a while without facing a serious crosswind. Then I had a check ride to fly the club's almost brand new Archer and was faced with a 17k crosswind...I really struggled and to my embarrasment the instructor said to me "I have control...just let me show you how to make this easier". In short I had got rusty in only several months.
Multiple runways I think do lead to less crosswind currency.
