Christmas Update: Ratings, Breakings, Noticings

Merry Christmas Eve KofCers!

Sitting here at my parents' computer, I was placed into a dilemma. On one hand I have a small, yet important, update to share with the KofC; on the other I have to use a dial-up connection to do all my internet browsing. My current connection speed? 40.0 Kbps, to put it in KofC terms I am browsing slightly slower than Daymonster plays Halo 3. What does this mean for you? A post devoid of links, pictures, or anything similar to entertainment. What you do get is an update on the ratings calculator...isn't that good enough?

I have good and bad news to report. I'll start with the bad. The previous plan was to use an Applet to put the ratings mechanism on the website. Unfortunately after I had the basic layout and design created and coded, I discovered that Applets cannot "talk" to other servers besides the one they are hosted on unless they are signed. What does that mean? Well it means I would have to go through a long arduous process to get it signed so that I can make connections to Bungie.net. Do I wanna do that? Hell no. The other piece of bad news is that after a series of frustrating events led me to punch the power cord on the back of my laptop multiple times in a fit of Dammer rage (see the ice scraper incident), the connection to my laptop has been compromised. Unfortunately both of my batteries are shot as well. What does this mean? This means that I placed an order for a new power supply today and it won't be here until next week perhaps. In other words production has come to a standstill on my end.

The good news: I have made a standalone version of how far I am in the ratings calculator. I plan to package it up and make it downloadable from the website as soon as I can get back onto my laptop. All you need is the latest version of Java to run it. It doesn't do anything yet, but at the least you will see what it graphically looks like. I will talk with Tilla some more, but until we figure some things out the plan is to make this a standalone app that will be available for download off of the website so that you can at least see what's happening. 

Random notes: I came home to find the Luther College yearbook placed in my room. How well was the KofC represented? Here's a breakdown:

DammerWillEatU: 77, 132, 139
Josey Wales: 77
Squatting Bear: 77
Locopollo: 77
Unky Warthog: 118, 120
Unky Eternal: no pages
UnkyPlayboy: don't know his real name

Based on this you would think that page 77 had a great picture of the KofC in action doing something, but you'd be wrong. Page 77 is the page for "Seniors Not Pictured".

That's it, enjoy your Christmas!

My Perfomance Rating Formula Suggestion

We all have been playing with the idea of some sort of efficiency index of some sort. Here is my suggestion:

PR=100*(((K*0.1)+(A*0.05)+(Sp*0.01)+(AL*0.001))-((D*0.1)+((B+S)*0.08)))
Where: K=Kills, A=Assists, D=Deaths, B=Betrays, S=Suicides, Sp=Best Spree and AL=Average Life (in seconds)

Essentially this equals out to a number between -500 and 500. 500 being a 50 kills streak with no deaths, and -500 being 50 deaths and no kills these extremes are obviously highly unlikely. Most PR ratings are between -50 and 150. A PR of 0 or below is pretty bad, where as a PR of 100 or over was a very good game, with the majority of our games falling in between the 0 and 100 marks.

I used this formula on the 7 games, Pablito, SB, Adeclipse and I played last night. The spreadsheet can be found here.

The highest two PR's of the night were by SB and Adeclipse. Adeclipse had a 115.3 on Guardian (13K/7A/6D/4Sp/63AL) and SB had a 114.9 on Snowbound (10/5/3/4/159).

The lowest of the the night was also by Adeclipse who post a lack luster -31.8 on Isolation (9/7/16/1/22), but to be fair that is his least favorite map.

I however never broke the 100 mark, unlike all of my teammates. Adeclipse had two games over 100 and SB and Pablito both had one. Everyone had at least one game at or below 0.

Here were the average PR's from the 7 games last night.
Adeclipse: 50.3
The Daymonster: 43.8
Squatting Bear: 30.5
Pablito Neal: 26.6

I am definitely open to suggestions to the formula, but once we are set on it, we can never explain it to anyone other than "It's complicated, and it takes into account a bunch of stuff", that way it will seem way cooler. The one thing I do like about this is how it works pretty easily with bench marks (i.e. Negative=Bad, Over 100 really good, etc.)
