This is the run data on a Cessna A185F N8081E,IO-520 with 3 blade Hartzell PHC-C3YF-1RF and 3 blade engine mount.
Incoming propeller balance was .272 IPS (Recently balanced with ACES system)
3 runs and 12.3 and 8.3 Grams weight added at 2 locations, IPS is now at 0.013 at 2173.4 rpm.
Run up to static Rpm of 2499 ish revealed an IPS of an incredible low level of .001 IPS!
Email the owner.. skywagon@bellsouth.net and ask him what it feels like!
Not all will balance this smooth but our goal is the best that is possible!
Here is the data from projects completed.

DSS has computed their industry average at .039 IPS, the average at Aviation Resources
using the same equipment is .02452 IPS.
Accurate measurements, attention to detail, evaluation of the
whole vibration spectrum leads to very low propeller balance IPS.

Our service documentation overview:
-Identifying tags placed strategically on prop/engine advising dynamic balance weights installed
-All forms printed on a laser or archival ink printer for archival permanence
-Two logbook entries printed on 'Sticky' paper; one for each airframe and propeller logbook (twins received sets for each engine)
-Multiple copies of the Pre Balance & Post Balance Spectrum and Waveform plots with annotations of items of particular interest
-An explanation and comparison of the Spectrum peaks as labeled for each particular engine machine file
-FAA Form 337 no longer required by FAA AC 20-37E 300. PROPELLER BALANCING. (c)(2)(c) For aircraft or propeller manufacturers that provide procedures for dynamic balancing of the propeller in their maintenance manuals or instructions for continued airworthiness, propeller balancing is not considered a major airframe alteration.
-All documents presented in archival quality document protectors
-Copies stored in multiple location for future retrieval; 1) Master record file in hangar, 2) Reference Logbook binder in hangar, 3) Billing records stored offsite, and 4) Hard drive back up at my house.
