IRI results appear in the TotalPave web portal almost immediately after the log is uploaded.
The only exception is the first time you collect data in a new area. In that case, the system first needs to create the mapped road line based on where you drove, then calculate the IRI results for that new line. This mapping process runs nightly, so first-time results are typically available the next day.
After the road line has been created, future runs on that same line process much faster and usually appear almost immediately after upload.
