6th anniversary scroll for one handed matk

I know the whole schpeel about junk scrolling and whatnot, but what I just experienced was my worst session of scrolling ever. After a long hiatus I decided to go all the way and finish my estaff 6 which was sitting at +6 from 6th anni scrolls (took about 16 to get there in total).thirty four 20% scrolls used to finish the seventh slot on my estaff 6 so I could hammer it then hopefully AEES it. None of them worked. 0.8^34=0.000507 meaning there's a 0.05% chance of this happening. Now do I deserve the I am an Unlucky Guy medal or is there something about 6th anni scrolls being glitched that I'm unaware of?
Also, apologies if this belongs in Q and A
