Hi David,

I'm aware of the other methods which mostly explained on your paper. Footnote 2 which clears up the definition "completely blind" was supposed to be "*No error is displayed and no indicators are visible in the response*" instead of "*No error is displayed and no indicators are visible in the response that an error occurred*".

Hopefully will update the paper soon, thanks for pointing it out.

Cheers,
