Uniqueness of systemsTraceAuditNumber and daily limits on Visa Direct OCTs and AFTs

I'm working with the "Funds Transfer API " and have some questions about the uniqueness of the "systemsTraceAuditNumber", and resulting application constraints.

 

According to the accepted answer for this question
https://community.developer.visa.com/t5/Getting-Started-with-Visa/About-systemsTraceAuditNumber/m-p/...

 

For a given AFT/OCT, the systemsTraceAuditNumber, retrievalReferenceNumber and acquiringBin combination must be unique in a 24 hour period.

 

Since our application would be using the same acquiringBin value for every OCT/AFT, and for each OCT/AFT the recommended format for the retrievalReferenceNumber contains the corresponding systemsTraceAuditNumber used in the api call.

 

These constrains seems to limit the number of OCT/AFT calls that can be made in a 24 hour period to the number of unique systemsTraceAuditNumbers available, in this case: 6 digit integer => 0 - 999,999.

 

Therefore our application can only make 999,999 OCT/AFT calls in a given 24 hour period.

 

Is this line of thinking correct and is there a limit of 999,999 calls in a 24 hour period?
