Dragonball is like most other comics severely inconsistent, when it comes to showings of speed & strength feats.
This is most likely because it ran for over 10 years and you can't expect the author to remember all the details of what they were capable of 10 years ago.
If we just discuss speed..
Krillin and Kamesennin at the 21st TB were so fast, that they had an entire fight scene transpiring in 1 second, which the audience wasn't able to see.
At the 22nd TB Goku was so fast that he became invisible to regular earthlings and even Kamesennin, who was able to see and catch bullets being fired at him.
And to top it all off, Goku and Piccolo at the 23rd TB were so fast, that not even effing GOD could see their movements and this is GOD we are talking about, the guy who is way beyond the Goku from 3 years ago.
By using powerscaling we know that the characters should have even more incredible speeds by the Buu arc and that Goten and Trunks are way beyond Goku and Piccolo from the 23rd TB, yet oddly enough people were able follow the fight, when such a thing should have been impossible!
Another example of DB feats being inconsistent is this..

Context: before Tao Pai Pai takes off for the Karin Holy Land
Tao Pai Pai: “It’s 2,300 kilometers northeast, huh?...Well the, I’ll be back in about 30 minutes.”
Note: So in other words, Tao Pai Pai says he can throw a pillar 2,300 kilometers, jumps on it and ride it all the way there, beats Goku, then come all the way back in about 30 minutes.
Tao Pai Pai is able to move his body at
over 9000!!!! km/h(actually over 9200).
Yet Buu arc Gohan..

Context: talking about Gohan’s commute from home to school
Erasa: “Eh! Did you say East 439?! You’ve got to be kidding. Isn’t that 1,000 kilometers from here!? [ ] How the heck do you get here? Even a jet flyer would take 5 hours to cover that distance!”
Note: Gohan later says he can fly this distance in about 20 minutes
Flies at 3000 km/h, which is less than
1/3 of Tao Pai Pai's speed
...so yeah..!
