Gap times for each Split and Rank type can also be called by appending to the Split field name. 

.GapTop	Gap time from the first Participant according to the chosen Rank
.GapPrev	Gap time from the previous Participant according to the chosen Rank

e.g. [SplitName.Chip.Gender.GapTop] will return the Gap time at that split according to chip time, from the first person according to the participant's Gender rank.

Gaps times are formatted according to the Contest time format except with all values capitalized (i.e. hh:mm:ss would become HH:MM:SS)

When using Splits you can also now call the Gap time according to the AutoRank if using the autorank in your output list. This allows the Gap time to change dynamically according to any filters which may be applied to your output list. 

e.g. [SplitName.AutoRank.GapTop] will return the Gap time at that split according to the same filter criteria used in by the AutoRank.

If a different format is required then the below options can be further appended to allow for a custom time format to be used

.Decimal	Will return the Gap as a decimal time (value in seconds)
.Rounded	Will return the Gap as a rounded time according to the Contest rounding settings
