I think we get to be incremented to 7. The last move I changed was #21; Aphelion played 23, 25, 27, 29, and 31 with no help from me.

Incremented corrections for Black, added turns without correction after (if Joaz approves it will be the first one).

This white group is still weak, having no eyes and no base. In those cases you either make a base for it, or run it towards the middle. Usually it's better to get a base first, but in this case I think running works well with the stones we have, and still leaves a possibility for invading the corner/side later.

This comes at the expense of making black's south side stronger, and giving them almost territory, but I think it's worth it.
I expect:

I'm not 100% sure this is the right move. However, it suits my style, and all other moves seem to concede too much. IMO White should have played there 1 point jump, and whereas directly cutting the keima may not always be best idea, I couldn't think of any indirect ways to profit from the weakness of that connection.

Here's some of my reading:

Things really branch out if White plays 6, but with Black having 1 weak group and White taking care of two, I think we'll be fine. Q7 can be treated light, I just need to be careful of the aji of o14 if this fight expands.

I agree, it is an overplay. Indeed, the previous white move was a bit of an overplay too.

This is why I think that it is an overplay: The usual direction of white in this joseki is to the side. (ie: north in this diagram )

White extends, black plays 2 like this, and there is a little tussle for corner eyespace:

...and then white counter-attacks the pincer stone with a, b. or c.

But when we put the joseki in the context of the game:

...now the counter-attack on the pincer makes no sense because of the black power to the north.

Not the best of trades, since it's gote, but it does give us substantial influence towards the middle and bottom.

An alternative would be to connect and fight it out, but that's what black wants:
