But sudden power ups arent the only issue, what is the issue is that it contradicts what was written and shown before in the manga, it's inconsistent and incoherent, your example isn't even remotely comparable(and as far as I can remember Naruto trained all the afternoon and implied to Iruka he had mastered kage bunshin).Not really. Its been this way since the very beginning. But the magnitude was not as high because they were just inexperienced and weaker rookies then. And time between consecutive scenes like today's was greater and there was story between. As we are now reading the war arc, it gets highlighted more. I remember Naruto as an academy student couldn't create a simple clone to graduate. But when he sees Iruka in danger from Mizuki later, he suddenly manages to create hundreds of solid shadow clones which he supposedly learnt from reading some scroll. Kishi has always given sudden power-ups to every character in desperate situations.
