Re: 1836's Steamworks Calculator!

Just to keep you in the loop - I'm working on this. Thanks for your input. I'll update soon.

The counting of the fuel for Match points need to be corrected to be additive between the all types (Auto High/Low, TeleOp High/Low) and not separate scoring lines.

Examples directly from 4.3 Scoring in the Manual (beginning with TeleOp to remove Auto issues and using 1/9ths for clarity):

12 in Low, 5 in High = 3 kPa, 3 Match Points
12/9 + 5/3 = 3
1 3/9 + 1 6/9 = 3

14 in low, 5 in High = 3 2/9 kPa, 3 Match Points
14/9 + 5/3 = 3 2/9
1 5/9 + 1 6/9 = 3 2/9

The calculator is showing both examples as 2 Match Points because it is treating each goal as a separate scoring line when the manual says that they are added together via examples. You don't just lop off the remainder in each goal before adding them together. At most, you would be off by 1 Match Point in the TeleOp part of the calculator, but see 2016 Einstein for how important a single point can be. The additive error doesn't end there though and can add another point of error when Auto is included.

The example given in the Scoring rule is 17 Low in Auto gives 5 2/3 kPa. An additional 3 Low in TeleOp will add 3/9 (1/3) to that giving 6 kPa. The calculator is not adding them together that way resulting in only the 5 still (it takes adding 7 to TeleOp low to make it add another point).

The kPa column should be showing the value in 1/9ths for TeleOp, 1/3rds for Auto to correctly show what the running total is without rounding. The Match Points column should probably not include the fuel as without having all 4 pieces of information together and calculated the total can be off by up to 2 points if the remainders add up to over 2 additional kPa:

Auto Low - 2 fuel - 2/3 kPa
TeleOp High - 2 fuel - 2/3 kPa
TeleOp Low - 8 fuel - 8/9 kPa
Total is 2 2/9 kPa or 2 Match Points. When put in the calculator this way, it shows 1 Match point and that is on the Low TeleOp line for some reason.



TLDR; The Match Points for the goals should not be separate lines but total for all with their respective weights based on goal and when scored. Calculate:
(Auto Low/3) + (Auto High) + (TeleOp Low/9) + (TeleOp High/3) for kPa (1RP if >40) and then round down to whole number for Match Points from fuel.


I can't download the Excel version to look at the formulas being used at the moment (errors out for me) but the above should help to make them act like the Scoring section describes in the manual per my using Excel to make sure I was seeing what the manual was saying. I didn't post screenshots as all you need to do is enter the manual's examples to duplicate what I was using.

Re: 1836's Steamworks Calculator!

Per 10.4.3 Qualification Ranking D. Each Team on an ALLIANCE that achieves at least 40 kPa receives one (1) Ranking
Point.
I've not looked at your calculator, but am just checking that you're clear you only need 40 kPa, not 41.

Currently the calculator is looking for the value to be greater than 39 (aka greater than or equal to 40).

However, I'm personally a little unclear because section 4.3 says
Quote:
If ALLIANCE exceeds a threshold pressure of 40 kPa
and I read that "exceeds" as over 40.

Anyways...was waiting on a clarification but for now counts how you said.
