Let's say you normally get 5%/y augmentation, but you can leverage a job offer to get 20%, that's 15% more. If your salary is 100k usd (55$/h for 35h/w), then that translates to 15k. Assuming it takes you (6h x 6 potential companies) 36h, that's 420$/h (assuming you work the whole year).

All this to say, with charitable estimates, this seems very worth your time.
