Which position do I see most on, lets say, move 7 in a specific opening?

Which position do I see most on, lets say, move 7 in a specific opening? And which position is next?

I want to check my scores in the most common positions so I can priorities my opening studies. First I thought to follow the most played moves upto move 7, but that fails because I miss transpositions. 

Is this the opening tree? That is not what I am looking for.

Here I can see that I have faced this position 94 times (manually adding 48+31+11+2+1+1). Now I want to know how this position compares with my other lines in the Scandinavian. The only way I can do this here is to handpick another line, and another and another (I did two lines below as an example, one line i faced 41 times, one 5).

I don't know how many different move 7 positions I have, but certainly too many to keep on handpicking... .

Examples:

Seen 41 times.

Seen 5 times.

I had a look at Openingtree.com and watched a youtube tutorial. It does more or less the same as the chess.com opening tree in showed as examples. In indicates that a position has transposed (nice feature) but it doesn't provide me with an overview wich lines I have played most (on let's say move 7).

Don't you all want to know this? What line should I learn best?

Opening tree is crazy ! 1.c4 Nf6 2.d4 e5 3.e3 is the 3.e3 Budapest Gambit Declined, yet when it plays through my games it knows I play 1.c4 e5 2.e3 Nf6 3.d4 which is a transposition to the 3.e3 Budapest Gambit Declined line that it fails to recognize.

It also recognizes 1.c4 d5 2.d4 dxc4 3.e3 as the Queens Gambit Accepted : Old Variation with line continuing on ...... 3.e5 4.Bxc4 exd4 5.exd4 Nf6 6.Nc3 but not the transposition 1.c4 e5 2.e3 Nf6 3.d4 exd4 4.exd4 Nf6 5.Nc3 dxc4 6.Bxc4 which is the same position of the Queens Gambit Accepted : Old Variation .

Opening tree is terrible at opening theory !!!!!!!!!!!!!!!!!!!!!!!!!!!!
