Changing the maximum age for the first split will automatically adjust the age range for the next one. Changing “And above” for the second split to an actual age, will automatically add a third split. From there, “And above” may be adjusted to an actual age to add as many splits as are needed for the event. Changing the age range for any split after that will automatically adjust the ages of the splits above and below that one. If you expand the age range of any split to encompass the entire previous or following split, the unneeded split will be automatically deleted.
