Weird VAM data from outdoor ride

Hi everyone, I noticed something weird on my last outdoor ride. The VAM data seems to be discrete in its behavior, it seems like I am comfortable on specific vertical velocities and not others.

My horizontal speed seems to be very continuous, but my vertical speed seems very discrete. I do not know if this has to do with my performance or the way the wahoo computer calculates it , but it seems very weird.

Anyone else has seen something similar or am I just graphing data that is nonsese?

thanks in advance.
