How is Wonder Woman's power in TV Show?

WW TV show is definitely a classic portrayal of Wonder Woman, and I've been a fan since I was a kid. However her power seems to vary pretty much in episodes. 
For example, in Season 2, Episode 17, she runs to the IADC building at nearly 1000 km/h, three times the speed of sound. Yet, in many other episodes, she struggles to catch up to a speeding car or bus. Similarly, while she can easily deflect bullets with her quick reaction time, but she could not run from the gas in front of her in many eposides. In the last eposide of S1, her belt was even removed by normal men in human speed.This issue also exist in invulnerablity, in S2E9, "The Man Who Could Move the World," she withstands a nuclear beam that could cause damage equivalent to a volcano eruption. However, in other episodes, she is defeated by something as mundane as chloroform.
So, how would you define her powers(strength, speed...) in TV show?

She has one ability. Plot armour

She's as powerful as 50s tv Superman

The explanation is IITS - it's in the script.

But it can be frustrating to 'experts' such as ourselves when powers are over the place because the writers don't care about the same things we do.

Exactly - whatever is needed for that specific episode.

The best/worst example is in "Phantom of the Rollercoaster", where she can't catch a guy who walks with a limp!

I think the show is the last place to "research" anything. I would say it took itself seriously once in a while, but for the most part accepted it was campy. 'Course, despite all this Lynda will always be THE iconic WW, and pretty sure awakened... the reason we - ok - why I'm here, along with Helen Slater (I would have been a grade school kid around the time of the movie and TV re-runs)
