The recommended texts are way longer than the originals. Engagement decreases per word written.
After all, if only number of words written mattered, the best thing to do would be to just have an empty slide.
Being concise is better than verbosity all things being equal, but not at the expense of failing to clearly get your point across.
I actually thought they were quite good.
Original: "Survey results"
Suggested: "Survey output indicates main root cause of churn is awareness of better value for money offering."
My suggestion depending on the context would be: "Survey: we're too expensive" or "Survey: churn due to cheaper alternatives" which will be read by 5x more people.
I, for one, think the specificity is worth the extra couple of words.
