I have noticed discrepancies when withdrawing troops from a pan. Let me illustrate with an example.  Assume I had 4,200,000 defense power in   a pan.  I withdraw 100,000. the garrison report initially shows  a new  defense value of 4,100,000 which is correct. When the troops return to acropolis, the garrison report  then showed 3,950,000 in that pan. I then attempted to return 50,000 to bring pan back to 4 million.  when they arrived back in pan, the garrison report showed 3,990,000  or 10,000 less than the desired level. This type of discrepancy appears to occur regularly. if units were put in pan with champions  does this create a timing difference in the  new defense calculated  for the Pan?  There were sufficient units (example: cavalry units ) left in pan to support the champion bonus,

If there is a delay in the garrison report correctly showing defense value for pan troop movement, is there  a best practice way  of removing troops  to ensure accurate values in garrison report
