Blood is negative, green is positive, from top to bottom from left to right.

-1.5 -3.0 +1.0 +3.5

-4.5 -7.5 +6.5 +8.0

Taking the copper ax as an example: The distance from the green to red of the PS is 116 pixels, each two pixels are a scale, and the scale is 0.5, so the forging demand is 29

The forging requirements of this copper ax are+6.5/-3/+1, so the progress of 24.5 needs to be calculated

Therefore, this forging is: 3 stamping +24, 2 impact +2, 1 lightly hit -1.5, and then forged the last 3 times as required.
