We don't call it beta for nothin'! |
Thanks for the quick response. |

Our team's average comes to 6.32715. The official scoreboard shows 6.3271. Shouldn't it be rounded up to 6.3272? |
Was it 6.32715 even or 6.32714xxxxx? |
I put all our scores into Excel and the top 4 scores' average came to exactly 6.32715, so I'm thinking the DPC rounding algorithm needs to be tweaked.

| It looks like it is taking the top 4 scores, regardless or not if 2 of the scores are from the same person because our team is correct, but our top 4 came from different people. |

Some teams the average is higher than the top score.

Did a quick check of team Dodge&Burn (whom we played.) They're score is close. It just did not round off to 4 decimal places.
DPL shows 6.3271 but they have a score of 6.32715 = 6.3272. Off by .0001

Resolved, yes?
It was a silly bug where I was including players that were actually removed teams during sign-ups. Click Click Boom was benefiting from someone's 7.0 :). |

Thanks langdon for the quick bug fix.
Is the rounding a bug or anomoly? Should it be resolved?

It could be a bug, what's the general feeling? I'm currently relying on MySQL's AVG() function, which I gather is rounding "0.15" down to "0.10" -- Edit, yea: "The behavior of ROUND() when the argument is halfway between two integers depends on the C library implementation. Different implementations round to the nearest even number, always up, always down, or always toward zero."

Check out this definition of rounding on Wikipedia. Specifically, look at the algorithm for the "Round-to-even" method, also known as "Banker's Rounding"...
1- Decide which is the last digit to keep.
2- Increase it by 1 if the next digit is 6 or more, or a 5 followed by one or more non-zero digits.
3- Leave it the same if the next digit is 4 or less
4- Otherwise, all that follows the last digit is a 5 and possibly trailing zeroes; then change the last digit to the nearest even digit. That is, increase the rounded digit if it is currently odd; leave it if it is already even.
