Feis Math…What is it?

Feis math is the art and science of determining approximately when your dancer, or dancers, will be competing on stage at a feis. It is art due to the need of understanding both the particular feis you will be attending and the quirkiness of this thing we call Irish time. It is science because, well, math is actually involved. 

Grades Math

During the week leading up to a feis, the voy boards light up with 100s of folks asking how to figure out just when their dancer will dance. (Ok, 100s may be a bit of an exaggeration.) I figured I would post my oft-used math here, in hopes of it being a helpful reference. And it's easier to copy/paste a link to a post here than it is to type the formula every week. :)

Calculating grades math requires knowledge of how many dancers will be on stage leading up to a competition. It is also handy to know if dancers will be going 2 or 3 at a time. Lastly you need to know what time stages will start. With those 3 pieces of information, you have enough information to do feis math.

Basically, you add up all of the registered dancers on a given stage and divide by 2 or 3 (representing the number of dancers dancing at a time) to arrive at the number of groups that will dance. Then, you multiply that by 1.5 (represents the time each dance takes, about 1 ½ minutes), which gives you the total minutes it will take those competitions to run.

Here’s an example (see photo): Your dancer is in competition number 1145M, on Stage 4.

1) Add up the registered dancers on Stage 4: (5+10+11+15+15+10) = 66 dancers
2) Divide by 2, assuming 2 dancers at a time: 66 / 2 = 33 groups
3) Multiply by 1.5: 33 * 1.5 = 49.5 minutes
Assuming a 9am start time, competition 1145M would begin around 9:50am.

Various events can have stages run faster or slower than the math predicts (this is the art part). No shows, late starts, holding a stage for a dancer or dancers currently dancing on another stage, judges who write too slow (just kidding). Any of these can affect how fast or slow a stage runs. Once you’ve been to a particular competition a couple of times, you can get a feel for whether they typically run fast or slow, or even have a habit of moving competitions to other stages that have completed for the day.

Hope this is helpful!

Yay! Thanks!

I hope to do a similar how-to on Champs feis math, mostly a tutorial on how to use the fabulous Peter Smith calculator.

This is great! Now if only someone could help me understand my little champ's "grid scores"...

Thanks. I'll surely take a look at it. Anything that can make it less confusing is good!

I thought the ceilis would take forever at one feis and walked into the room with my reel group lining up! Barely made that one!

Yeah, ceilis are hard to guess. Whenever they are first, I almost decide to start whatever is next on stage with the feis start time, just to be sure I arrive early!

I just want to let everyone know that I used this valuable "math" to figure out the stage schedules for the Verlin Feis this past weekend and it was almost spot on!!

There were some minor stage problems that always one can take into account. however, it made our three hour drive to the feis less stressful. We made it with good practice time to boot!
Thank you thank you!

In the UK (I'm not clrg) it usually starts at 9am with youngest age group and runs through dances per age then level. So u13 usually start after lunch. Most feis organisers will let you know what time they would like you there.

I have found this formula to work well as an approximation for when to arrive at a feis, while actual start time is usually 30-60 minutes AFTER the estimate, and my DD mostly competes in Mid-Atlantic region feiseanna. They almost always run late (once almost 2 hours behind), my guess being when stages share musicians. Also, when stages run late keep checking in case they move a comp to another stage, which happens later in the day.

Yes, when stages share musicians, the math gets really interesting. What I typically do then is follow the 'longest path'. Meaning I calculate the times based on the highest number of dancers (on either stage). It makes things quite interesting, that's for sure! I've started keeping notes for myself about which feiseanna run stages sharing musicians (whether it be 2 stages, 3, or 4), so I can run the math the best way possible.
