As someone with a learning Disability (ADD) I never did well with maths and although I can do this mechanic it takes longer that the 12 or so seconds. I either miss it or Just get there in time depending on what I am given.

The community needs to realise on the other end of the character is a human being that could have a disability mental or physical and they WANT to try and if they are trying their best then we need to accept it and help in anyway we can without being d**KS to those actually TRYING.
