Thank you.

I've done a great deal of tinder testing and reviewing, too. A big overview of my results can be viewed here:

I don't want to sound too critical, but you are testing pieces of tinder of dissimilar size and weight to achieve your results. For me, at least, it is more interesting to equalize by volume or by weight, and test burn times and flame output per the same quantity of each. When I need to start a fire, I use the amount necessary, regardless whether it is less or more than a single officially sized piece.

Also, keep in mind that there's a variety of other parameters to assess as significant for tinders, such as waterproofness, windproofness, durability, packability, ease of preparation, etc.

Additionally, not to sound rude, but: If it's taking you an average of two strikes to ignite a vaseline soaked cotton ball and 6-8 strikes to light Tinder-Quik, then there's either something suboptimal with your tinder prep, or with your firesteel technique, or both.

Personally, my choices for best tinder, all factors considered, are:

1) Fatwood
2) Tinder Quik
3) at this point, there are many I view as about equal, overall: vaseline soaked cotton balls, trioxane, methanol, etc.
