Too much compass varience

another flight done with suggested parameter

if mu drone require compass calibration before flight do i have to burn these listed parameter again since the value goes to default .

There should be no calibration of compasses required, that would be a step backwards.
Even if you travel a long way from home compass calibration will NOT be needed - recalibrating the compass for every flight or location is an outdated concept tied to early DJIs.

I didnt notice anything different in that log - are you going to try Autotune on pitch and roll axis?

should i proceed with auto tune my drone, which flight mode to set for auto tune.

which flight mode to set for auto tune& should i proceed with auto tune my drone

You set your flight mode switch to have Autotune as one of the modes, so if it’s a 3 position switch you might have Stabilise, AltHold and Loiter. Then change Loiter to be Autotune in the arducopter parameters.
Select the pitch and roll axis using the AUTOTUNE_AXES parameter.

Make sure you have lots of open space, the copter will drift around a lot during autotune, and you can reposition it periodically.
Take off and fly around to check everything is working OK in AltHold.
Switch to Autotune mode and wait until it completely finishes twitching. DO NOT switch OUT of Autotune mode, just reposition and land with the sticks and throttle as per normal.
Wait a few seconds after the copter disarms, then you can change flight modes and test fly.
Remember to put back Loiter instead of Autotune once you’ve done all axis.

done with auto tune sharing bin file of auto tune process and another flight in loiter mode

note: i have notices values were same before and after auto tune in PID setting
