Piano Finders Standard Test Results

On Scale of All Pianos

Includes pianos from 36” spinets to

9’6” concert grands

(PFS Scale effective date 1/7/2000)

**PFS Test Results

Conversion Formula.

For converting the results

on the PFS scale of All Pianos

to any other PFS scale:

**Formula for converting ratings on Scale of All pianos to various PFS scales:  where x = % on any scale 1 through 5 and y = % on Scale of All Pianos, z  equals maximum % on scale of All pianos that can be achieved at 100% on any PFS scale.

x = (y times 100) divided by z

The following gives the value of “z” we used in the PFS Test Results Conversion Formula** for each of the following scales:

1.      Scale of 5’ & under Grands

* For the purpose of  the PFS, we assume that the piano will receive 1 hour of standard use per day in a humidity-controlled environment.  We have also based our opinion on service record for similarly constructed and designed pianos. New parts are not always more durable than original parts because they may not be as well made, seasoned, etc. Because of the uncertainty in predicting the future, this particular piano may end up being more or less durable than predicted in the rating.

The PFS Test takes into account the following reports performed on a piano:

R1.0 Piano Values Report: to determine market &  investment values.  Summarizes the R1.2 & R1.3 Reports and gives values before and after various levels of repairs.

R1.2 Piano Inspection and Evaluation Report to determine the extent of piano upgrade that would be necessary to bring piano up to the standard of it's own potential as well as less extensive upgrade options.

R1.3 Piano Upgrade Recommendation Report to determine the cost of repairs for each level of upgrade.  Recommendations are made as to which repairs will be most cost effective and will produce the best  results for  various customer's needs and values.
