Numbers system for training

Does anyone remember Kevin Rooney's number system he used to use with Tyson?He had assigned a number to each different punch and he would call out number combinations and Tyson would throw the punches that went with those numbers.

I am thinking of incorporating this system into my training and also want to use a letter system for kicks.For example a 1=jab and A=leg kick so 1A would be jab+leg kick.

Does anyone remember the specific numbers he used with the specific punches?

Miller. I love the Bas Rutten system's simplicity for drilling.

1 - jab

2 - jab cross

3 - jab cross hook

4 - jab cross hook cross (or uppercut)

"3 hooks" - left h. right h, left h

"liver shot" - left body hook

ex. 1, 4, 2, 3 + livershot, 1, 1, 4, 3, 3 hooks...

For mt purposes follow up the last punch with a kick or knee from the opposite leg.

ex. 3 = jab /cross/ hook/ roundhouse

"10 knees" - 10 skipping knees.
