Sorry for not responding quite long...
The escape rate formula is on bulbapedia iirc.
Also the guide was not originally written for DP as I have little or no experience there, it was written for RSE/FRLG.
The Berry Powder formula I can't even remember where I got that... It happened a time ago when I just had FireRed myself. But I used the formula on ingame numbers and it worked very accurate.
For the Pay Day money, the formula's I find all boil down on the same result, which is in the guide...

Thank you for posting some mistakes indeed, the critical hit thing was very obvious and the stat formula looks better I agree.
Feel free to change stuff and it would also be a very good idea to convert it to LateX to make the formulas look better... I'm not very familiar with using LateX but the documents always look very good.
