More ripping

Yesterday I ripped that black top two times again. I realised, that there must be a mistake in the pattern: two yo's, and one knit2tog, makes one increase, right?
So, this is why one row never would end, and this is why one ball cotton made one
cm fabric...
I did not want to risk to modify the pattern, (neither I was feeling to make a swatch, I just feel I would waste my time, silly, isn't it, when bad gauge make you rip ten times...) so I looked for a similar pattern in one of my pattern books. I found a very similar one, but that time it was too late to make any progress, so I finished only 4 rows. I hope this night I can continue with this pattern, and I won't need to rip it up again.
Another cute picture instead of those knitting ones:
