On the face of it, your self-assessment of your points seems wrong to me based on what you have posted.
For example, you have given yourself 5 points for having a post graduate Specialist Education Qualification - that is a Masters by research or a PhD in one of the nominated areas (Computer Science is one). ACS have equated your qualifications to a Bachelors degree - this doesn't cut it.
You have also claimed 5 points for the Australian Study requirement. Have you actually studied for 2 years in Australia?
On the other hand, assuming you have certified experience of between 3 and 5 years from ACS (I can only see 11 months in the letter but there may be more that you didn't post) you should have got 5 points for that.
You may be entitled to 55 points but probably not more than that.
