The gem doesn't increase strength exponentially by the second. More accurate is linear as Thor never showed a dramatic increase (less than 2x more) in all the time he had the gem.
Assuming Odin is at most 10 times stronger than normal Thor (which is an exaggeration) then Thor with power gem should be thousands to millions of times stronger after an hour with the gem, assuming exponential growth by a decent growth factor. But Thor couldn't even bust out of the block after a very long time. And Odin did in several seconds. I admit, Odin could have used magical power to aid him instead of pure strength.
Finally, Thor only started to really draw from the gem in effort to break free from the block. Before that he drew only to send back Stranges blast.
