It was hard to tell on all except one where the heat range was at (3rd one from the right). The one i could see looked like it was right at the bend but others looked like it was hot towards the tip.

That actually tells you initial and total timing, not actual load heat in the shell.

Edit: by the looks of the plug you held up, you are a bit short on total timing.
