Generally, if a question already has an answer (regardless of acceptance), any new answers need to bring something new that wasn't mentioned in a current answer. This can be something the answer has missed, something that contradicts the existing answer but has merit, a deeper analysis of aspects of the previous answer, or something which interprets the question in a new light and provides a solution to a prerequisite problem in the original question. In addition, we prefer answers which are less susceptible to changes, AND answers with a credible and accurate source.
In your case, you bring new information, namely hard numbers. However, hard numbers like these tend to be really volatile. If Valve decides to change the base EXP that creeps reward, but not the percentage that denying grants, your answer becomes outdated. The accepted answer doesn't become outdated if the base EXP changes. Both your answers become outdated if the percentages change.
your answer also does not have a source for the EXP values. The accepted answer doesn't provide a source either, but it appears to come straight from the path 7.07 patch notes. That makes it more credible.
