I disagree. Most people uses the mempool data wrongly, for eg. reading the chart after successive blocks gives a fee rate that is far lower. You can't predict the future, but it doesn't help if the user don't know what to do with the data. Simply telling them to aim for the top 1vMB of the chart with their fee rates is insufficient.
Of course tools like this site are mainly for "advanced" users and it is always best for others to choose a decent wallet with a good fee estimator and stick to that or at least use this alongside that wallet.
Correct me if I'm wrong, but in the case of a so-called burst of transactions, they are not divided evenly between blocks?
Sometimes there are services that "burst pay" their users. For example I remember freebitco.in paid on weekends, so basically we saw lots of transactions go out at once which means most of them would be in the same block.
