Walk speed exploit/bug while encumbered

[Sunems]

Hi

I have wondered this for a long time and I finally got around to posting this:
When you are heavily encumbered and can only move at a snails pace (think 45-50 kg), I have found that if you crouch and and get back up again without breaking your stride, you will move faster, albeit only slightly, than before you crouched. This effect persists until you stop moving and, if I recall correctly, I have been able to do this since the game launched and still am.

I have been feeling increasingly bad for using this, in my own opinion, unfair exploit and hope you can help me with either fixing it, and save me from temptation altogether, or assure me that it's by design, and let me crouch-n'-stride with my head held as high as my enormous backpack will allow.
