chart update interval with 1 sec charts

Does 'chart update interval' affect study calculation results when bar lengths are low, say the 1 sec second interval?

For example, if you have 'chart update interval' at 1200 ms, and are using 1 second bars, do calculations get out of sync? Would you have bars that get skipped over in calculation in a case like this?

Or does a study calculate at the end of every bar regardless of what the chart update interval is?

Thank you

Similarly, if I want the most efficient setting for 1 second charts in real time...

If 'chart update interval' is set to 1000 ms, is this 'chart update interval' calculation time exactly synchronized with the end of bar calculation (if there is one, see above)? Or are these on separate clocks?

Anyone?
Thanks

I actually am finding this to not be true in one case...

I have a study which is based off your study that sums charts. It sums the volume of whatever charts are open, more than 10 charts

The historical calculation is identical- it does not depend on what the chart update interval is.

However, once the real time calculations begin, I get different results depending on chart update interval.

I am sure to clear the subgraph data to zero before each loop through the charts (to gather the volume data up). This still does not give a consistency.

See attached.

I think I found the solution... GetBarHasClosedStatus

sc.GetBarHasClosedStatus()
