Before Brock
After Brock
Notes:
I grinded a bit for the Exp Boost quest (4 evolved pokemon before Brock, was Caterpie->Metapod->Butterfree, Weedle->Kakuna and Charmander->Charmeleon). Even without it the exp felt decently fast/fast especially that catching a pokeon rewards the win credit.
EDIT: I have a double Caterpie since the first idea of the overhaul i had that the evolved/preevolved forms require same exp amount to level up (and it's correct up to level 10 at least ^^)

Notes:
I just moved through Mt.Moon and i got into the 2nd gym as my first thing in cerulean - I've left the Nugget bridge and onwards for later, but I was considering clearing it if I had any serious problems. Overall - was pretty good.
