Score Tracker when a team fails to field a jammer
« on: November 07, 2011, 07:40:54 pm »
So this actually came up last night, I was score tracking for a team where the team failed to have a jammer on the track before the first jam whistle was blown.  I know how I recorded it, but is there a standardized way to record a jam in which a team did not have a jammer? 

If you have an opinion on how to record it, that is great and welcomed. If you have a definitive answer, a citation would be most appreciated.

Thanks!
Any night when I can pull up the covers and say "I am a better ref right now than I was when I woke up," is a good day.

My suggestion would simply be a dash in the jammer-number box, perhaps also check the NP box.

I'd agree that some sort of indication that there was no jammer should be put in so somoene reading the form understands that the number wasn't omitted but the scorekeeper wasn't able to catch the jammer's number.  I'm not sure I would mark NP as that gives an implication that the initial pass started but didn't finish.  I think I'd just fill in the jam number, write no jammer fielded or something to that effect in the jammer number box and leave the rest of the line blank.

Agreed, just was thinking of whether a computer somewhere might read that line as incorrectly filled out without either a number or a checkmark. (If it did, I'd then tell someone to redesign the form with a checkbox for "no jammer".)

If you are filling in the WFTDA Stat Book Excel Spreadsheet you'll probably want to enter something like a "-" in the jammer number (there are large chunks of the spreadsheet that check to see if a given cell is blank, and if so, ignores the rest of the row, including some erroneous checks where it looks at the wrong cell*).

However, all skater based stats are calculated based on the number entered in the IBRF, so anything that doesn't match is ignored (and since there wouldn't be a skater with "-", no stats will be gathered for a skater numbered "-").

Jam/Score based stats like NP will still work - the no pass column should still total up to include that.

However (and I'm going to have to do some spelunking to double check this), if the extra blocker is entered into the lineup sheet in the jammer column, they will be treated as a jammer for the purpose of skater stats (and so that skater will be listed as having skated a jam as jammer).

One possible work around is to adjust the height of the lineup tracker cell where that skater is entered to show the second (hidden) row and enter something there to indicate "not jammer".  The stats will still be wrong, but in theory one could adjust the formulas to try to take that into account - I've been contemplating that to deal with a local team that usually doesn't field a pivot (I then do my own analysis using some custom Python scripts I've been working on)


*If you have more skaters in the visitor section of the IBRF than in the home section, the skater summary stats & VTAR will be wrong because it ends up ignore some of the data for those extra visitor skaters

Hmm? If a team doesn't field a jammer, you signify that on the lineup tracking sheet by using a slash/dash through the field for that jam number. You would never record a fourth non-pivot blocker in the jammer field; and you can never have five blockers on the field. Well, a jam might start with five blockers (or two pivots for that matter) but you wait for the refs to clear that up before you attempt to record the information.

I agree, there is no fifth blocker just an ineligible jammer that is not in proper position and it isn't my job to sort out who that is. 

I would probably actually write a notation on the paper sheet just to be sure I can tell people what happened with that jam and use a - or something on the workbook.

In general I want to fill my paper sheet out in a way that I can be pretty sure I can recreate things (yes I have added small notes with asterisks) and I assume that being in the zone of watching for the next thing will work much like brainwashing and cause me to forget.

So what did you end up doing?

theMadStatter, that's a good thought. I should probably dig through the spreadsheet myself and see how some of that is handled.  In answer to the question, I put N.A. which in retrospect (Not Applicable/Available) makes it look like I just didn't get the number.  But I didn't check the NP field, and I think it's probably correct not to check the NP field.

Was the first time I had encountered it as a score tracker, and I still think it would be great if there was a general consensus on a standardized way to handle it.
