@Roy: You just have to come to Germany.
How far are you from Berlin? There's a very, very, very, very small chance that I may be in that area in Nov.
About 600km (almost other side of Germany). Let me know if you come to Berlin. Maybe I'll visit some friends there.

Hey, Leipzig is about 4 1/2hrs from Munich and 2 1/2hrs from Berlin! Why don't meet half-way? But even the trip to Berlin would be worth it to meet one of "the masters of SQL Performance & Martial Arts". 🙂

Note that I've received a complaint on this thread.

I don't think anyone has crossed a line, but I see a few posts that are close. Please remember that this is a public thread, and your comments are public, and they reflect on you.

It is one thing to vent about posts or mistakes, it's another to directly call someone out of insult them. As I said, I don't think anyone crossed my line, but it's close. Please be professional in your posts.

Along the lines of that rather strange comment on SimpleTalk a week or so back (asking for BioTech books iirc), I thought this might provide a few laughs.

It looks like my code got partially garbled when they tried to format it for the article. I have attached the actual code in a text file for your enjoyment. 🙂
:laugh:
The in-line version became slightly garbled too!

Luckily, the attachment worked just fine, and is just outrageous - but so cool.

The funny thing is about a week after I submitted that, I came up with a cople of different compression schemes that are almost twice as efficient. I guess I'll hold those for the next time. 😀

Has codez, needs brainz . ..:-P

Ok math geeks. My poor little head can't wrap around why I get different results for these, and hoping you can help.

Trying to determine the average utilization per thousand member months of a service rendered (CPT code). Looking at it per thousand months in order to nullify the impact of membership growth.

I need to come up with an average from 1/1/2007 until the end of June 2009.

Two schools of thought:

1 - calculate the utilization per thousand (util per K) each month,

sum up all those numbers and divide by 30 to get the average (30 months between 1/1/2007 and 6/1/2009, and codes don't appear in every month)

2 - just take the true utilization since 1/1/2007 and divide by the member months for the entire timespan.

I had assumed that these would be equivalent. D'oh!

Why are these numbers so drastically different? Which one is more accurate?

I'm going to be applying this rate to projected membership, so I'll be multiplying by 200,000 or so to find future utilization per code, that's why it makes such a big difference.

Example attached, I inserted data with zero utilization for the missing months.

You know all of the UtilPerK values for code 11975 are zero in the second half of your table? That's pretty much always going to drag down any comparison.

Yes, I know they're zeroes. That's to counteract the average being too high when the code isn't present in the utilization at all.

Anyway, the zeroes are in both methods, so that shouldn't be the problem. (says the guy who can't figure it out):-D

Is this a case of the "average of averages" not being equal to the "average of the total"? You should never assume that those to be equal.
