Percentile Rank After the Log Is Cleaned

A platform team logs the latency of 480 API requests. Use the percentile-rank definition from this course:

$\text{percentile rank of } x = \frac{\text{count of values} \le x}{\text{total count}} \times 100$

In the original log:

• Latency 150 ms has percentile rank 65.
• Latency 400 ms has percentile rank 95.

The team then cleans the log in two passes:

1. Every request with latency strictly greater than 400 ms is traced to a single misconfigured client and deleted.
2. A further 30 records are found to be duplicates. All 30 have latency at or below 150 ms, and all 30 are deleted.

No other records are added, removed, or altered.

In the cleaned log, what is the percentile rank of 150 ms?

Round to 2 decimal places.
