[phenixbb] PHASER-TFZ scores with ensembles higher?

Dear Phaser users,

I recently tried to solve two difficult MR jobs by using ensembles in  
With ENSEMBLES in this case I mean aligned structures prepared for PHASER  
by Phenix.ENSEMBLER.
In both case I got solution with rather high TFZ-score (> 8), which I  
couldn't get wit individual structure, but was not able to refine them.

My question is, whether using ensembles would increase the Z-Score without  
really improving phases. In other words, if there is another cut-off for  
the "Phaser solved it" Z-score, when using ensemble in contrast to single
