Side door play

If I pull my sliding side door shut slowly I can feel a slight jumping of the centre rollers as it turns into the closed position in the stainless guide.May have always been so but not noticed.With the door half open,if I push/pull the door at the rear centre there is feelable play.would not have thought it's worn at 6 months old.
Question to p.v owners....how much play in your doors?

May have worded my post and made it sound more complicated than it need be. What i am trying to find out is ....If you grip the rear edge of side door in area of the centre roller and pull and push towards and away from the van have you any play?
Mine moves a couple of mm and may be normal, I am just trying to see if that is so.

 It does on my Warwick Duo (not an XL)

Thanks for the reply spospe. 
Do you also get a bump in the stainless track as roller turns into the closed position?

Kemerton-bath....Thanks for testing and results,1cm and alls fine.
That's more than mine so I may be a bit over cautious'especially as it bumps on turn in.The reason I am so cautious is my van went to Peugeot in its first week with door open and closeing issues and has been back 4 times since (post in Feb).They have done various adjustments and changed a cable.It is much improved but I feel it could be better.Their professional advice is that it's a commercial van and I should slam the door a bit harder,why did'nt I think of that?!!!!! 
Anyway from what you imply they are all a bit different so I quess if it opens and closes what's the problem

I believe you can get electric closing side doors now on X250 vans, but maybe only on the Fiat versions, not Peugeot.
