If the cone bent, you're good to go, unless something odd happened that knocked the cone out, but that's very very unlikely. I wouldn't fret. My L&L e18T-3 (18 x 27 inches) kiln can get to 04 in just over 4 hours.
I only use my kiln setter to fire. You'll be ok.
Thanks for the feedback, its very much appreciated. :0)
