QR Hacking (Artefact #3 Continued)

During my research into error correction I found a website which allows for QR's to be hacked. When looking into how this worked I found that up to 30% of a code can be edited and a phone will still be able to recognize and comprehend the data within. Obviously as more of the code is changed the more tempramental it will be but I found that in all the cases of scanning different codes myself and my volunteers came across no problems and had a 100% success rate. Below are the codes they were asked to try.
