Root Velocity Tracking Error in paper

[Breezewrf]

Hi, thank you for your awesome work!

May I ask a question about the Root Velocity Tracking Error described on paper

Based on Table 1, the Root Velocity Tracking Error of approximately 0.3 under no-force conditions appears to be significantly high？(On average like 10deg/s angular and 0.15m/s linear error exist)

Thanks a lot!
