Makes sense to me Chad.
Being a rookie I was having a tough time getting a puddle due to low amps. Once I used a more aggressive max amp setting it allowed me to hit it quick and hot, similar to a tack weld, to get the puddle started then back it down.
Miller's phone app notes to add 10% to the amperage setting for mild steel vs. stainless.
Your post got me thinking......if it was a CNC process the machine would probably monitor material temp ahead of the bead and the amperage would gradually be stepped down from start to finish as heat builds.
I thinking about videoing my machine readout while practicing to better understand the process. Similar to a Dyno chart or GPS track log for an event.
