No this is not the case. People just think it is because the first graphs have really big changes and the second graphs generally only really small onesFirst time you get a good roll bank it. Then roll to improve it if you've got the materials.
Ok thank you. I spent several hours last night kitting out my AspX for material mining (no refinery) and hit a ring. After finally working out the nuances of mining (including arriving at my destination without having bought any limpets) I didn't find any arsenic. It seems I need to visit some planet surfaces instead.
