Plastic thing + hot glue = perfect jumpthrow

So in team pracc we discussed if you can do a perfect jumpthrow with two keys binded, one for "-attack" and one for "+jump". And then a guy on my team ironically said that, if its so important why dont you just glue the two keys together. I actually thought the idea was good and decided to do it myself.
How it works: The plastic piece is glued to the keys "K" and "L" so when i press down it will press both keys down http://i.imgur.com/7R5NG9a.png. I tried this map https://www.youtube.com/watch?v=Crrq4tMKM7M and got consistently 7ms delay (i know that 7ms is not 0ms but i always got 7 ms so it is pretty consistent) as shown in this picture: http://i.imgur.com/zanDgz7.jpg I tried doing the map with two buttons binded and the closest i could get was 7ms which means that my plastic thing is just as good if not better (because i always get the same "score" on the practise map) than pressing two buttons at the same time.
Thats it, the onkly probklem is that i have glkued my "kl" button and my "lk" button together wich makles it klind of hazzkle to type words with K and L. EDIT: I have plans for a concept wich includes being able to detach the plastic piece from the two keys. I will make a new post if that happends.
