if i understand what you are asking, there are 5 rows of a-b-c... in script above the numbers
the first three have rounded transitions between letters and the last two have pointed bottoms
notice that there is more pressure at the very beginning, then as you travel south, you ease up and the middle of the stroke is thinner
(sometimes called waisting)
then at the bottom as you are applying more pressure to end the stroke, the widest part is at the very end and when you know you are at the end you lift up
- letting the tines snap closed and at the same time, make a slight motion to the right to create that little point.
it would take me a while to get in the groove to do them perfectly since it happens pretty fast.
i don't think you can do them in slow motion, but, i could be wrong about that.
there are all kinds of subtle motions that can make a difference.
sometimes you can rock up and make the nib more vertical - to make a pointed ending.
and it looks like he might even leave the pen down and the stroke leading into the next letter comes out of the previous stroke just slightly above the pointed bottom.
so there might be a pause at the bottom - and you could rock your hand with that pause.
i remember watching Michael teach at IAMPETH and he bounced along with that beautiful rhythm that you see the masters executing.
as Sheila Waters says, when you are analyzing a style of writing you look at 7 characteristics and no. 7 is the speed.
some of the details are functions of speed.
hope that helps
