Hi Jose,
when you clone Pepito, it remains a Pepito clone.
When you clone TSCP, you will have thrown almost all data structures and
replaced a bunch of routines by the time you improve it by 200 Elo.
By the time you hit +300 Elo, you probably have a complex bitboard engine with
no trace of TSCP in it. That is the difference.
Regards,
Matthias.
