No you're the one claiming it was about raw power when it doesn't need to be. Trunks didn't punch him nor did he pour his Ki. Your examples are irrelevant to this instance since they demonstrate more power in one of those two ways and those quotes just further elaborated.
Here is an example...
No it doesn't always mean stronger juat becasue you say so. Trunks used a technique to push him back. Tien and freeza have shown to do similar things. Power is shown through either Ki, or the damage that their strikes induce.
It can mean stronger but that doesn't have to always be the case every time that word is used. Trunks displayed a technique and not raw power, so it wouldn't have to be interpreted as such.
The base saiyans are at the same level from the androids Arc. They were never shown or stated to have increased their power further after hitting the wall.
