What is the distribution of the most common delta times per bin?

Each bin is of size 80,000

What are the outliers when comparing max and min delta times?

Which release did the worst job?

Are delta times consistent across serial numbers?

How much useable data (+/- 1 hour) is there?

Further Analysis

Our team determines the following questions are too complex for Tableau and require custom scripts to be written.

• (Pick out the system serial numbers that have useable data and return the ones that have consistently accurate data)
• Determine an error range for acceptable delta times to indicate whether a system is reporting according to standards or not.
• Determine the proportion of usable delta time in each release.
• Determine the trend of delta times over time for specific systems
• Determine the cause of poor delta times, whether it be the release, FW version, SW version or controllers
