Wow!  500 registered users!

Last month I mentioned that this website had a record number of new visitors.  I honestly thought that was an anomalous one day spike in traffic.  Instead we’ve had a sustained increase in new visitors and people signing up to use the workers’ compensation calculators for free.

Since February 13, 2009 ((When the 400th user registered.)) I’ve enjoyed posting about:

Ever since I relaunched this website I’ve had this idea in the back of my mind that getting to 500 users would be a big deal.  There are literally hundreds of workers’ compensation professionals who rely on this website and its calculators to make their lives a little easier.  This certainly feels like a big deal to me.

I had an interesting e-mail exchange with a friend (and fellow workers’ compensation professional) the other day. ((Photo courtesy of Street Fly JZ))

We were discussing the impacts of Ogilvie on 2005 schedule ratings.  He had asked me whether I intended to update the 2005 permanent disability rating calculator to include FEC Ranks after the scheduled 8.  I believe he had suggested FEC Ranks 9 through 20.

I have no intention of manufacturing FEC Ranks 9 through 20 for the following reasons:

  • Maintaining Standards. The entire point of a rating schedule is to allow a standardized method for calculating disability and expressing those disability calculations.   If I invented my own FEC Rank system beyond the scheduled 1-8 Ranks, I would essentially be creating my own rating calculation system.  I’ve gone to considerable lengths to ensure that the rating strings produced by these permanent disability calculators are as standardized, recognizeable, and universal as possible.
  • FEC Ranks are Irrelevant. The FEC Rank system is a simplified method of applying DFEC adjustment factors.  When you use the FEC Rank of a particular body part to adjust the standard using the charts on pages 2-6 and 2-7 of the 2005 PDRS (permanent disability rating schedule), what you’re really doing is essentially multiplying your standard disability against the FEC adjustment factor associated with the particular FEC Rank for the body part in question.  An FEC Rank is only useful for telling you the appropriate FEC adjustment factor to apply to the standard disability.  Thus, FEC Ranks are irrelevant and FEC adjustment factors are all important.
  • Arbitrary FEC Ranks. FEC Rank 1 has an FEC adjustment factor of “1.100”.  However, using the Ogilvie DFEC rebuttal formula, it is possible to end up with very low FEC adjustment factors.  In extreme circumstances it would be possible to have a negative FEC adjustment factor.  The only way to resolve this would be to have several possible negative FEC Ranks.  Besides being somewhat silly, worrying about additional FEC Ranks ((Both higher and lower than the normal 8)) misses the point.  If you’re using the Ogilvie DFEC rebuttal formula properly, the result will be a new FEC adjustment factor.  If you already have the FEC adjustment factor, you have no need for the FEC Rank!

When I had discussed the impact of Ogilvie earlier, I had pointed out that in some cases the resulting formula will dictate that you use a different FEC Rank than the one indicated by the affected body part.  In other cases you will need to use an entirely new FEC adjustment factor.  In order to keep the 2005 disability calculator current I will eventually have to create a way for the user to override a body part’s standard FEC Rank and specify a new FEC Rank or their own FEC adjustment factor.

I’m not in any particular rush to develop this feature since Ogilvie seems to require three years of post-injury earnings.  I doubt we’re going to see litigation begin in earnest over Ogilvie issues for another 18 to 24 months.

February has been a wacky month.  And, on Friday February 13th the 400th user registered for this website.  ((Photo courtesy of atxbill)) Since the 300th registered user, quite a lot has happened:

I launched the Ogilvie DFEC Rebuttal Calculator on Saturday morning to a select group of beta-testers.  ((By “select group” I mean anyone who asked me if they could help.)) When I upgraded a person’s access to the website they had no problem seeing the workers’ compensation calculator.

Unfortunately, not one of them was able to actually use the thing.  Last night my wife suggests the problem might be, “maybe they are using a different version or its not refreshed or something”?

And you know what?  She was right.  My wife, the hacker. ((Photo courtesy of gutter.))

I’ve written several protections into these calculators to insulate my users from having to deal with problems or bugs from newly installed code.  I would much rather a user sees nothing than get a wrong answer.  And nothing is exactly what my users saw.  I had remembered to allow my beta testers to see the Ogilvie DFEC Rebuttal Calculator – but forgot to give them access to calculator.

So, the beta-test period will continue for another day or two while I await feedback from my users.

If you’d like to see what the Ogilvie DFEC Rebuttal Calculator looks like or want to try to use it, just sign up for free and shoot me an e-mail asking for access.

I’m going to delay the launch of the Ogilvie DFEC rebuttal calculator for a day or two.  ((Photo courtesy of mhuang))  I believe it works just fine, but I would like to test it a little more.  This said, I will grant anyone who is interested access to this calculator.

Why the delay?  Well…

The interesting thing about taking apart a set of calculations is that you find all sorts of “hidden steps” to the calculation.  The majority in Ogilvie does a respectible job of going through the steps of this new formula and even gives several examples.

When performing most calculations one will need to round numbers at some point.  However, rounding almost invariably takes place at the very end.  In the case of the Ogilvie calculations, it appears that the WCAB rounds various figures throughout the calculation.

Even though the DFEC rebuttal calculator was giving correct answers, the fourth or fifth decimal places on some intermediary figures occasionally did not coming out right.  It took me a little while to track down all the spots where the WCAB was implicitly rounding their figures (and to what decimal place!).

I am fairly confident the calculator will work without a hitch, but I’m going to test it a little more before I make it available to the public.  If you’re interested in testing this Ogilvie DFEC rebuttal calculator, please drop me a line and let me know.

If you’re not a registered user for this website, its free to sign up and free to use all the workers’ compensation calculators.  Seriously, free as in free!
