it does both...depending on your goal.  it can be used to make bow less centershot but also reduces contact patch on two points of arrow as it is shot...reducing potential misquies from bow arm to arrow during this critical time of flight.

Ain't TradGang the berries?    Ask a question and get a nice education, resources, and difference of opinion. Love this sport, these people and the priviledge of doing it.

Placing a toothpick under the strikeplate means you are tuning your bow to your arrows. You make the bow less center cut, allowing you to shoot arrows with a weaker spine.

Bingo!

Yes it does in my opinion. The smaller the contact point, the less any bow torque will effect arrow flight.

even more so if those contact points are directly above the deepest part of the grip.

I like using a rubber band instead of a toothpick...it's more forgiving imo.

i use yak sinew taken from a northern yak killed on the southbound trail of a Himalayan mountain pass that was milked by Buddhist's under the stars of the winter solstice....i find it adds 5fps and I can drop my bow arm before the shot and it will still hit the bulls-eye.                

If I have an arrow that is close to being in tune, that I don't want to cut shorter, and it is still a little weak, adding something thin like a little strip of leather or a paper match under the side plate is a great way to bring things into final tune.

Ron,
I need to get me some of that, can you spare any?  

Ron, you shouldn't be letting all of the god secrets out!!

I think you should be selling that yak sinew by the inch! It sounds
like amazing stuff!

Does it come in single-bevel with a lot of FOC?

kharma baby, kharma!
