Yeah top 20 is a little excessive because in my own tests I found that top 20 is only marginally more accurate than top 10. You can get a more academic explanation [here](https://www.tandfonline.com/doi/abs/10.1080/09296174.2011.53...). I was amazed too because it seemed too easy!
FWIW, top 20 was necessary for mine. The bolding was a brilliant move. Several of my accounts were ranked 10-20, but popped out due to the bolding.
What does the bolding indicate?

As far as I’m concerned, it’s the killer feature of the app. The top 20 results may be noisy, but the bolded results have a signal to noise ratio close to infinity.
