FASTER CHARTS: Declare ONCE_PER_BAR; How does this work?

TOS Description:

Changes the recalculation mode of a study. By default, last study values are recalculated after each tick. If this declaration is applied, the study is forced to recalculate the last values only once per bar. This declaration can be used to reduce CPU usage for studies which do not need to be recalculated per each tick.



Q: Does Declare ONCE_PER_BAR calculate at the START of the LAST BAR or the END of the LAST BAR or something else?


Q: Have "heard" that Declare ONCE_PER_BAR allows a LIVE LAST BAR, but updates everything left of LAST BAR only "once per bar" - is this true?


I guess the best answer would be a complete description of this function by TOS, but to no avail. : (


Any ideas? Any references?
 
I just added the declaration to the RSI indicator on a 3m chart and it does only update once every 3m with it in place but I'm sure that wouldn't be the case with all Thinkscript functions... So I'm assuming that its compliance is subjective depending on the functions used in a Study...
