Before looking at possible twinning problems ( I guess the experts will 
strike soon ) I would also suggest, given the resolution, to feed the 
starting model to ARP/wARP (www.arp-warp.org) and let the 'warpNtrace' 
protcole rebuild it. If that does not work and R/Rfree are still high I 
would start (well ... keep on ...) being worried ;-)
