Names
iSplit uses names to find information about Racers, Rosters, Meets, and Races.
Positions
iSplit allows you to order Rosters, Meets, Races, and Splits by Position.
Times
iSplit uses the format
“hours : minutes : seconds”
to display times. Seconds are displayed with three decimal places. iSplit stores times internally as milliseconds.
Distances
iSplit uses meters, kilometers, yards, and miles to display distances. On screens displaying units, users can click the unit name to cycle through the units to set the unit used and the distance will be automatically updated. For distances measured in meters and yards, iSplit will display the distance as a whole number, for distances measured in kilometers and miles, iSplit will display the distance with three decimal places. iSplit stores distances internally as centimeters.
Racers
Racers are the individuals who participate in the meets. Every racer must have a first and last name and the «first name, last name» pair of every individual must be unique. Although the system is set up for individuals, you can use it to collect team split times in relays, just create a fictitious individual representing the combined effort.
Paces
Racers have an associate pace. The pace of a racer is updated with every «split time, split distance» pairing. This can happen if the racer has a time associated with a split and you set the distance of that split or if the split has a distance associated with it and you set the racer’s time for that split. This pace will be updated everytime you change the racer’s time or the split’s distance. Setting the time to 0 or the distance to 0 will remove the split from the racer's pace. Deleting a split will not change a racer’s pace, so this information can be retained from one meet to the next even if you clear the races from memory after each meet. Paces are used to order racer’s names at the start of a race (faster racers will be at the top of the list) and are used to provide an estimated time of arrival while timing a race. If the pace information is becoming too out of date to be useful, you can reset all the racer’s paces.
It should be noted that paces may “double count” some sections of a race. For example, if a racer has competed in a two mile race, with a split time of 5 minutes at the first mile and 12 minutes at the second mile, then there will be two contributions to the racer's pace: a contribution of a 5-minute mile for the first split and a contribution of two 6-minute miles for the second split. If these are the only splits for the racer, then the racer's pace will appear as 5.667 minutes per mile. The pace iSplit reports will be a weighted-average of the racer's paces.
 
Rosters
Rosters are collections of racers. A racer can be on multiple rosters. A roster’s primary use is to make setting up a Race easier. If you have a group of individuals who frequently race together, place them onto a Roster. A Roster’s name must be unique.
Meets
A Meet may refer to a single event (e.g., an event with a single race) or may be used to collect together related events. For example, at a Cross Country Meet, there may be multiple races associated with the meet (e.g., Boys Varsity, Boys Junior Varsity, Girls Varsity, Girls Junior Varsity). The Meet’s «name, date» pair must be unique.
Races
Races are single timed events. Each race has a timer associated with it. Racers do not enter Meets directly, but are entered into Races. A Racer can enter multiple Races associated with a Meet, for example, at a Track Meet, a Racer may compete in both the Boys 800k and the Boys 1600k. Another example of multiple races would be the Tour de France where each Race may correspond to a day of the meet (in which case almost all Racers would be included in all the Races). The Race’s name must be unique among all other Races for that Meet.
Identifier
For each Race, you can assign each Racer an identifier. This can be useful if the Racers are assigned numbers in the Race (for instance, if they are wearing bibs). If a Racer uses the same identifier for many Races (for example, if you are tracking NASCAR drivers), then it may be better to include the number as part of the Racer’s name.
Splits
Splits are places along the course where the Racer has a time. Splits are typically associated with a distance, but it is not necessary to have a known distance for every split.
