Vertical touch weight

I just got home from tuning and evaluating a Gulbransen console 1954. 
The customers complaint about the acton was that it was too heavy, not
something I normally run into with consoles.

Down weight was 69 gms., up weight 21 gms.  giving me what I presume to
be 24 gms. of friction.  If I can get that down to 10 gms. the down
weight should come to 55 gms.

Are there standards for verticals?

Are my ideas off?

My plan is to repin wippens and hammers, possibly reduce hammer return
spring tension, refelt wippens and lubricate action areas as possible.
