Worth a look if you are interested in the physics and to see how Justin’s lessons develop over time.
I now find I have done 110% of G1; not sure how that is.

I want to know why Justin’s guitar double dot inlay marker even at the 7th fret just like 12th?

Manufacture’s preference. Some guitars have no dots at all some have squares, stars or parallelograms. There is no rules as to how many dots are on the neck. Just where they are situated on the neck.

Just wanted to point out that the “12 equal steps” are equal only in log frequency space.
Or to put it in another (mathematically equivalent) way, the ratio of the frequencies of each step are the same.

How many octaves are there? In theory can there be an infinite number of octaves? And in practice how many are used?
Octaves = frequencies connected by scale factors of half or two so yes, I would say the number could be said to be infinite.
Placing the concert pitch note of A4 in a cluster.
A1 = 55Hz
A2 = 110 Hz
A3 = 220 Hz
A4 = 440 Hz
A5 = 880Hz
A6 = 1760Hz
A7 = 3520 Hz
And so on …
A 24 fret guitar has five octaves of the note E. See this diagram.
Notice that apart from the lowest and the highest, the other E-notes can be found in multiple locations on the fretboard.
