Specifies the minimum percentage of speedup required for a prefix to be considered improvable when generating the Executive Summary snapshot report.

Must be in report configuration mode (config-reporting), which requires privileged-level access.
Use the exec-summary improvable min-percent-improvement command to set the minimum percentage of speedup that must be achieved by switching from a BGP route to the CNA choice before a prefix is considered improvable in the Executive Summary snapshot report. Percent improvement (time saved relative to final time) is calculated by subtracting the HRTT measurement across the CNA-chosen link from the HRTT measurement across the slowest BGP-selected link, dividing by the CNA-link’s HRTT, and multiplying by 100:
If you have multiple edge routers, there will be multiple BGP-selected routes. The percent improvement shows how much better the CNA choice performs than the slowest of these BGP routes.
This percentage is one of two criteria used by the CNA report-generating process to determine if a prefix should be counted as improvable. The other is time savings. The prefix must meet both conditions (minimum time savings and percentage speedup).
Use the no exec-summary command to reset all executive summary parameters to their defaults, including those set by each of the following commands:
Use the no exec-summary improvable min-percent- improvement command to reset only the minimum percentage value to its default.
