We're talking about this issue though. I have explained my problem with their methodology and their results.
We'll I'm still not sure what your problem with YouGov's methodology is, you've said that you don't trust their panel and that you don't believe it is reliable but not why. Their methodology appears to work for other polling what is it about the Scottish Independence question that makes it inaccurate? Or do you believe that all their polling has the same problem?
If they really cared about their polling on this issue (no-one will give a shit after), all they need to do is change their sampling population and apply the same methodology.
Sorry I must be missing something here, the same methodology to what?
Ipsos Mori have had much more random variation around their estimates than YouGov.

Those are the polls from both companies and TNS-BMRB since Dec 2013. Ipsos Mori do show a greater change than YouGov and TNS-BMRB but trying to extract any meaning from the fact is nonsense, there are only 3 IM polls and they have been taken over a 9 month period where opinions could/probably have changed anyway.
