Just as a matter of interest - from the numbers above you say 62
blueprints approved - was this only for this cycle - or *up until* this

When you mention several up for review - can you elaborate on exact

I am not looking to 'monitor' activity - but for me it would be
interesting to understand - what the workload is actually like. If the
ratio of 'incoming work' (blueprints) vs. completed/in-review is 62:3
then to me - this seems to be something that needs to be addressed.

Or am I misunderstanding the comment above?
