Focus stacking help please

[broch]

Hello,
I am trying to master focus stacking, however I am not able to achieve as much as I wish.
I have 60D with nightly from 11/07.

This is what I am able to do:
go to focus menu
-highlight Focus End Point and press Q. This is your 0 (starting point)
-Focus Stacking menu select:
Num pics in Front 1
Num Pics behind 6
Focus Steps/picture 1
- Focus Settings and set
Step size 2
Step delay 50ms
Step wait ON
Start delay 2

This works well, however numbers of pics is set arbitrary and often requires adjusting/running stack again.
I did search forum and youtube and I found this tutorial:

from 2:18
This is done on 5D mk2 with ML from few months ago. What I like is about this tutorial is that end point is set with joystick. Unfortunately this method does not work form me on 60D/recent ML - number of pics is taken from Focus Stacking menu rather than from joystick.

Evidently I am doing something wrong. I would appreciate your help/suggestions.

Thank you
