Calf strain and KT tape

[avocado]

I have a slight calf strain and have touch footy on Friday night.
Wondering if anyone knows the best method of using KT tape or similar.
The strain is toward the outside, about 2/3 way up between ankle and back of knee.Sorry, I don't know the anatomical term.
There are dozens of different methods on youtube and most of them contradict each other.

Some say a cross. Or a Y. Or one up the middle. Or stabilise the ankle first. Stretch the tape. Don't stretch the tape.

Honestly I don't think they do anything. My physio put it on me for my shoulder but he said it was just as a guide so I could correct the posture in that area.

Using it in sports where you are dynamically changing positions frequently wont provide much support or structure.
