Sorry its taken so long to reply
You asked about the frequency of the spasms
They are pretty much on a four minute cycle - during the first three minutes of each cycle just the toe twitches and tremors on a regular basis - eventually this builds up the the whole leg shaking from the thigh down for the last minute of the cycle, then the whole thing starts again
The frequency can be made worse if Ali has a knock - which is inevitable when the leg is so "active"
Hope this helps
