Why do you think thickness would effect burning time?
Well, a burning piece of fuse will have a specific temperature I imagine. Each unit volume of burning fuse cross section will emit a certain amount of heat before it burns out. The larger the cross sectional area of some small length of fuse dL, the more heat will be emitted. The more heat emitted, the faster the next slice of fuse will ignite. The larger the cross sectional area of that next slice, the slower it will ignite.
What this means is that if a thick section of burning fuse is adjacent to a thin section of fuse, the thin section will ignite quickly. If a thin section of burning fuse is adjacent to a thick section of burning fuse, then the thick section will ignite slowly.
By the way, this
