One Run per Row
Key One Run per Row in Task refers to an optional boolean that determines how many times the function ƒⁱ should run when the respective iᵗʰ row is processed.
The default is FALSE, whereby each row is processed only once with the corresponding function ƒⁱ running R times, where R is the number of elements in each array contained in the Values of the Key-Value pairs specified in the corresponding cell of the column titled #VaryingInput
If set to TRUE, when the iᵗʰ row is processed for the first time, the corresponding function ƒⁱ runs only once using as input the top elements of the input arrays mentioned above.
After all N rows - and thus all functions ƒ¹, ƒ², ..., ƒᴺ have been once processed in this way, the second round of processing starts with the rows being processed again from top to bottom.
When the iᵗʰ row is hit, its function ƒⁱ will run again once, but this time using as input the next-to-the-top elements of the respective input arrays, provided they exist.
If such elements do not exist, the function ƒⁱ will be skipped and processing will be transferred to function ƒⁱ⁺¹ at next row i+1
These processing rounds will continue for as long at least one function contains not-yet-processed elements in its input arrays.
