Has anybody come up with a way of testing r1 r2 on a ring besides the time consuming method of disconnecting cables at sockets/fuse board and doing the figure 8 test ?

Use a plug in adaptor for the sockets so you don't need to unscrew them. You still need to cross R1 and R2 in the board.
Which is still the 'figure of eight'.
You'll always have to cross-connect L+N, measure resistance at all points then cross-connect L+CPC and measure resistance at all points (highest is R1+R2).
I normally use a plug in adaptor but in some cases readings start to vary due to the age of the socket outlets (PIR - I don't use second hand sockets-outlets!!) so sometimes there's no alternative but to unscrew the socket from the wall.

I can't see any other way of doing it as any interconnections are not going to show up unless you do the cross connections at one point.
