Target Power Apparent Delay

Hi,

i am successfully able to control the target power on my FE (Kicker). one of the things i have noticed is that there seems to be a delay between the time the command (page 49) is sent down and the power page (25) is received. my logs show about 3 seconds. however, i can feel the resistance of the FE before i get the power page update.

i don't think anything is wrong, i am just wondering if this is normal. i paid special attention while doing a workout on zwift and although there is no log there i can see the target power change (for example from 150W to 225W) and i can feel the resistance in the FE a bit before the on screen display shows the current power change.

i've included a log snippet from my own app output, it shows the power being sent, the verification that it got there and a page 25 eventually. i wonder if this delay is partly related to my requesting page 71 4 times to confirm the message was sent by me.
