At this point they don't seem to have set any public goal and instead say it's a "study" to see what may be possible with new tools.

As of the current status, the bit rate reduction of JEM6, when compared to an HM16 soft-
ware encoder implementing the HEVC Main 10 Profile, is around 30 % in Random Access
(RA) configuration using motion compensation in a hierarchical B picture structure, and
around 20% in All Intra (AI) configuration (without motion compensation). This result was
obtained when averaging the bit rate reduction comparing at same PSNR by the so-called
Bjøntegaard Delta criterion
[...]
Measuring PSNR can be misleading as a criterion for judging quality. In order to assess
the subjective visual benefit, expert viewing tests were performed during the 7 th JVET
meeting in the context of evaluating responses to the Call for Evidence[...]Typically, bit
rate savings at same visual quality of between approximately 35 and 60% were observed.
Just read the doc from post #5 ...
