If you load up the game you can see the actual numbers. Numbers for abilities can be altered by any number of modifiers including your resource pool, your level, the skill's level, skill passives, mundus stones, etc. The chart for a simple change like that would be monstrous if they took into account every possible variation.

Its called homework.

They do not need a chart. Every skill has a base number that is then modified by other things by a certain coefficient. Making these numbers visible to all can only increase the amount of productive feedback (well probably the negative too but whatever) that players can give because they can more easily test certain conditions. As it is now without extreme testing it is hard to tell how well a skill scales because there is Base + (X * Stam/Magicka pool) + (Y * Spell/Weapon dmg). The more information they give the better the feedback we can give. Fill in the darn numbers for us so we can help test out the variables and don't make us rely on old posts or old logs to find out information you should have posted.
