Rating System For Grappling Moves

I admit there really isn't a reason to rate moves, but I did this because I thought it might be fun and also it seems people always want to talk about this. You often see questions about what the best move is or if this move is good or not, so maybe this will be useful for those that aren't familiar with certain techniques and you can get an overview before you dive all the way in. Please keep in mind that these are only my opinions of these moves and also these ratings could change over time. Years ago it was rare to see anyone finish an anklelock, but now they are finished fairly regularly. Hopefully this will be useful for those not familiar with certain moves and for those familiar with them, tell me what you think of my ratings and rating system. Now let's look at the criteria. 

Ease

Everyone is different however some moves seem to cause many people trouble. Sometimes it's because of the complexity of the move, for example worm guard. Other times the timing or feel of the move needs to be just right. I've had lot of problems with deashi barai because of the timing and the darce choke because you need to have a feel for where your arms need to be placed. Other moves like the RNC seem to work for just about everyone with little instruction. The RNC would have a high ease rating and the darce choke lower rating.

Universality

Some moves are known as big guy moves, others might require flexibility, etc. Universality is how well it works for a variety of different in people. The rubber guard might not work for everyone but an inside heel hook will. Obviously it is better when everyone can do a move and it isn't limited to people with a special attribute. 

Finishability

This is a rating of how easy it is to finish a submission. This is of course subjective and masters of a technique can make it work consistently, but we all know there are some moves that almost always work and others that barely ever work. This encompasses the opponent's ability to defend as well as how much wiggle room you have if your technique isn't perfect. An omoplata can be difficult to finish for almost anyone, but a choke from a crusifix will almost always get the tap. 

Usability

Besides submitting the opponent, does it have any other utility. Something like an omoplata is hard to finish, but it can often lead to sweeps or other submissions. Even if you can't finish it, there are reasons to use it. Many moves like the kimura or the omoplata have auxiliary uses that are sometimes better than their primary use. 

Accessibility

Some moves can only be done from certain positions such as the RNC. Others like the armbar or guillotine can be done from almost everywhere. The advantage of having moves that are more accessible is that once you learn them you can use them from a variety of places. 

Example

Here is my rating for the Kimura.
