I heard back from one source that related that they do the best they can to assure the testing piano "lives" in the same humidity year-round. It doesn't give us any info at this time about changes... They also indicated that it is possible for different groups to end up with (slightly?) different master tunings on the same piano - unrelated to change in humidity and temp - more a reflection of the group effort to make all of the related progressions as smooth as possible.
