For anything FIRST related the published data is fine. Even if the the published figures were 20% off (which i doubt they are), you are still limited to using the motors in the KOP. In FIRST there is generally a clear best motor option for a particular mechanism. I doubt that you could even use better data. Its not like we have motors whose specs are within 1% of one another and we are trying to figure out which one to use. I cannot possibly think of any way that you would need more accurate data.

Another issue to consider is that a FIRST team has limited money and manpower resources. Your time would be better invested elsewhere.

If you are doing this to build more competitive robots i think your time/money would be better spent elsewhere. If you are doing this to learn about motors and instrumentation then please proceed. You will learn things in the process even if they are not what you originally set out to learn.
