Gironda's Tempo?

Just checking out your article on Gironda CT, no mention of tempo. Your article says Gironda was always a stickler for form and control without kipping among other articles online which got me thinking about why I see no mention of specific tempo anywhere online. Any ideas?

Tempo prescriptions were ā€œinventedā€ much later than Gironda’s career. Ian King was the first one to strt using it in the late 80s/early 90s and Charles Poliquin popularized them.

I have a sneaking suspicion Ian King got the idea of tempo training from gymnastics. Gymnasts have always used tempo based strength training for bodyweight strength.
