Well, I believe that Excal have more than one set of limb deflection rating group in use, internally, at this time. Certain deflection number groups are "categorized" for internal use & identification of various meaningful and relevant limb characteristics, which provides them with the ability to monitor (through failures/failure types/speeds and other known collected data) limb performance and reliability and as a result, actually allow them to meaningfully predict limb performance and behaviors of each deflection rating group when targeted for/installed on each model usage case. So limb deflection rating groups is an advanced quality control tool which helps them determine which limbs may be the most fit for the job and most trustworthy for each model usage case.
This type of internal use rating strategy is a very smart one, as it helps the company to provide greater customer satisfaction, minimizes warranty claims and clears up a whole lot of muddy waters pertaining to limb waste... which is a factor inherent to pressure-mold limb manufacturing anyway, and is very difficult to control. Certain deflection groups that are poor fitting or provide known low speeds and/or high likelihood of failure if put into service are never installed on any models leaving the factory. Certain deflection number groups may be designated as fit enough to be sold as blem sets. While certain other deflection groups that will underperform/fail on high output models do just fine when installed on least demanding models.... etc.
I know that I have incomplete knowledge of their deflection rating system, but I believe that I understand them well enough now that I can draw certain conclusions in certain model cases that I have been able to find numerous recent reports on, and identify some of those group correlations. With all that said... I'm gonna drop the subject entirely and leave Excal alone. The last thing Excal wants or needs is the public to discover their limb deflection system. Been there, done that.... hence the need for occulted complexity which is meaningless information to the public.
PM me if ya ever decide to sell off your #61s PatK!
