Create stats and graph where it's displayed the AVG and SD of every single jump of an rj jump using:
100* (tf-tc)/tc (like DjIndex)
or
tf/tc (like Qindex)

1st can be called RJ Evolution Distribution DjIndex
2nd can be called RJ Evolution Distribution QIndex

As an example of Qindex:
1.- Rj of "Peter":
tf
.55, .6, .6
tc
.2, .2, .3

2.- calculation
a) find Qindex:
2.75, 3, 2
b) find AVG:
2.58
c) find SD:
peterRjJumpSD


2.- table shown at statistics window

peter (rj) 2.58, peterJumpSD
Youl (rj) 2.73, youlJumpSD

3.- plot something like:

|         -
|         |
|   -     |
|   |     * 
|   *     |
|   |     |
|   -     -
|
------------------
    P     Y

From the (*) to the up (-) there's SD, also, obviously from the star to below (-)
In this sample Youl has bit higher AVG, and double of SD than Peter.
