That might be the case for what you use power meters for, but it's not the case for all uses of power meter data, nor for everyone.Originally Posted by sitzmark .
If awards in competition were to be given out like awards for power lifting, then quantitative accuracy needs to be spot on. Since cycling competition revolves around distance vs. time, accuracy of power output is of no real (competitive) value. ... a nice to have, but not a requirement for what power meters are used for. IMO
As Robert points out, there are some applications for power data where a high degree of accuracy matters and can result in substantial performance improvement to be gained from such actionable intelligence.
