A second file called Updated Skyrim - Game settings.esp contains comparison of each level xp requirement table and modification of health, magicka and stamina at level up, improved weapon and shield bashing values, raises max armor damage reduction to 90% and disables encumbrance modification at level up; to make up for this while in game open console and type "player.forceav carryweight <whichever value you want, mine is 5000>" to set encumbrance limit to wanted value.
I made this change for more "elegant" gameplay, but you can disable this by going to Creation Kit -> Open -> (select my mod) ->
click Details -> select desired variable -> press delete and confirm.
All changes are made for balancing purposes. List of all changes is included with mod.
