Thanks for your comment.. The element generation rate of each upgrade is based on how much the planet costs to unlock, so expensive planets should give you more elements (exponentially).
if you had 1000 dmg pick, and 400% manual click, 200% auto click
your dmg would be 4k and 2k, if your auto click is clicking fast enough it would be more dmg than you clicking, but if you were fighting something with 2k defence, your dmg would be 2k and zero, auto dmg wont do anything, but clicking will still produce dmg
