Setting wire speed on a flux core welder without a chart

I am new to this forum and new to welding. Great site with great information.

I have been watching the MIG basics videos from Welding Tips and Tricks. I found the video on setting wire speed and voltage very useful. In particular, I thought that the short circuit MIG wire feed chart and calculations was great. Would this chart and calculations work with FCAW?

From the website and the videos:

"Based on the 1 amp per 1 thousandths of thickness of the metal being welded, there is a number that can be used for all the popular wire diameters that will give you a good starting point for wire speed.

For .045" wire the number is 1

For .035" wire the number is 1.6

for .030" it's 2

.023/.024" the number is 3.5

So the example giving is 1/8" or .125" thick steel.

For .030 wire, 125 x 2 = 250 ipm."

If this does not work for FCAW, is there a chart and calculation similar for flux core?

Thanks,
