Australian sport will be 50i, so 50 different images a second after deinterlacing. American sport as broadcast in America is 60i or 60p so 60 different images a second.
These comments were made back in 2008 by a reviewer in the United States:

I for one was not conscious of any noticeable lack of motion resolution last week when watching the nightly highlights coverage of the Rio Olympics supplied free to air on 7HD in MPEG-4 at 50i. Our set is a 65" 4K 2015 year Sony LCD TV that does not use frame blanking and which had motion interpolation at a default low setting. (This Sony set has a football mode. I've never experimented with it. I presume it would insert interpolated frames more aggressively.)
There are many video artefacts I do notice, plasma screen flicker being one of them, but lack of motion resolution due to sample and hold is not something I can say I have ever noticed with sport. (I do sometimes notice a breakdown in resolution caused by lack of bitrate for encoding a scene that contains fast changes but that's an issue with the source material, not the display device.)
Who here is experiencing problems with motion resolution with a modern LCD set when watching sport? Anyone? How annoying is it? What does the problem actually look like for your vision? How much better is the look after engaging aggressive frame interplolation?
Of course a lot of the sport we get in Australia is in SD with MPEG2 encoding at not all that high a bitrate. Any lack of motion resolution would tend to get lost in the general blur of SD, I would think.
I haven't been affected by any "problems" and neither have other people I know who have owned Plasma TV's for many years.
That's not to say that there aren't issues with various models, or with the way some people use their TV's, but its not the norm.
The alternative is to buy a TV with "issues" that would bug me ever time I watched it, that doesn't make sense as far as I am concerned.
The average consumer has very different needs and wants, to each their own.
