[Orgmode] Log Notes with Non-sequential states

[Deech]

Hi all,
I am trying to use the lognotestate feature to log the progress of a project.
However my projects go from WAITING to TODO and back to WAITING so there is no
definate sequence. 

Is lognotestate even the right feature to use? Is there a better tool to log the
actions taken in a project?

Thanks...
