ST60 Wind Linearising and aligning transducer at the dock

[beckett]

I have replaced my older transducer and need to do the "Linearising and aligning" procedures. I currently can't sail out of my marina due to shutdown and was wondering:
- instead of doing two circles with my boat I went up the mast and turned the wind indicator slowly two times. It seems like ST60 took it, however, I just wanted to make sure it was OK?
- also, the manual says to align the wind direction to enter the calibration mode and "sail into the wind and adjust the analog wind indicator angle to zero". My question can I just do it at the dock without taking the boat out and adjust the wind angle to what it is by entering offset to indicate the current wind direction at the dock?

Thank you in advance for your help!
