Yep, dangerous to read too much into possession stats. As mentioned above, our possession is low by design (not accident). Numerous managers have achieved success this way, Jose for one. It's about having a style of play which gives you the edge over your opponent (admittedly this hasn't happened this season).
My main gripe is that some of the newer players are probably not accustomed to playing this way and we may actually benefit from a style of play centred on ball retention. I'm not sure if Warnock has this in his play book?
