How do you configure IncreaseRecoveryRateStrength in GreyFace's mm6 mod?

The patch notes say

'Increases rate of Recovery' enchantment now works. IncreaseRecoveryRateStrength controls how much it increases the rate. Default is 10%.

But it doesn't say what to put in the config file to use it. Say I wanted to make it 50% (like the original game intended.) Would I put IncreaseRecoveryRateStrength=50 or IncreaseRecoveryRateStrength=50% or IncreaseRecoveryRateStrength=.5 or how does that work?

According to source code, this value has type of "int" (see script in github repo):

int 'IncreaseRecoveryRateStrength' Info "[MM6]"

This means it cannot be "50%" or ".5", so correct usage is:

IncreaseRecoveryRateStrength=50
