NetForecast's investigation of comScore's ISP speed test methodology uncovered the following data gathering errors:
Only one TCP connection is used
Client-server delay is variable
Participants' computers may be resource constrained
Test traffic may conflict with home traffic
Decimal math is incorrect
Protocol overhead is unaccounted for
Purchased speed tiers are incorrectly identified
Figures.
Obviously we need to spend more money on government so they can do better testing to convince us we need to spend more money on government.
