Clarification of Range/Height ratios in BR Physics I

[Rucap09]

Going through the BR physics book and came across this passage:

"The maximum height that a projectile can possibly obtain is h (possible only with a launch angle of 90 degrees) while the maximum range is 2h (possible only with a launch angle of 45 degrees)."

Yet in the table for Range/Height ratios 30 degrees has an R/h of 6.7 and 45 degrees has an R/h of 4.0.

Am I missing something or is the first passage an error?

Nevermind, I just realized they meant maximum range across all angles (which occurs at 45 degrees) is twice maximum height that occurs at all angles (which occurs at 90 degrees), not range/heigh in same launch.
