No, you're wrong and I'm telling you how. The weight of the water being lifted is increases as each *section* is pulled, but is otherwise a constant for each section, until the foot is above the well level.
BTW, it's not "poly". The OP's well pipe is iron.

Yep, I was thinking the same thing last night.
As to the effect of water in the pipe _below_ the static level I dreamed up a good mind experiment to show that it has no effect.
Rig a pipe with a valve at one end that can be closed. Submerge the pipe with valve open 10' into water - weigh pipe. Leave pipe there and close valve - weigh pipe. No difference.
