So many "unknowns" that us folks in cyberland can speculate about this piano and the general scenario. Is this "non-computerized colleague" well experienced in voicing European hammers (he might have been an ace at voicing NY Steinways but have little experience with dense hammer felt)? Etc, etc (i.e. the "unknown" variations are endless). Who knows whether the player is stressing the instrument needlessly or is a very moderate player? Your colleague may be well served by asking you to "do a consultation" (including observing the pianist at play), probably after that chat with the dealer and the Petrov tech rep (preferably with them amenable to paying for your time and expertise).
