Capacity of MC on VA-HR

I am evaluating the VA-HR as a platform to host my pebble app.
The Programmers Guide lists some run-time errors such as :

• Too Many Timers (what is the limit?)
  
• Too Many Arguments (is 9 the limit?)
  

I know this isn't exhaustive, eg. Too Many Objects Error:
Before committing resources to porting the app, I am looking for a comprehensive specification of the actual capacity and limits of the platform.
Is such a document available?
