@Raichin Sakura was stated at least once to have a more effective Byakugo and she donkey punched ninja-goddess, breaking her horn off... she surpassed Tsunade. If you mean time-skip as in the blank period, then I have to ask what do you mean by that?

Even before Naruto and Sasuke got six paths chakra, theu surpassed their sannin masters pretty easily.

Orochimaru admitted to not having a chance against EMS Sasuke. I'm pretty sure Sakura surpassed her before or after the time skip, but she did indeed surpassed her. Naruto was able to control and then master tailed beast chakra and sage mode along with it.

So they kind of did surpass their masters, way before the blank period. Just about the time they did the three lockway summon again.
