There has been an update for the powerful BWChart bringing the latest build to 1.03B. Pretty small update, but some of you may find it more significant that others. The new version now allows for a better view of the APM and where it is going. Here's what
JCA had to say:
BWChart 1.03B introduces a new APM chart that can display both Micro APM and Macro APM. The new APM curve can be displayed by checking the "Macro" option at the top of the screen, when watching the APM chart. It is now a standalone chart. Resources are drawn on a separate chart.
The actions a player makes has been put into different catagories.
Select Units Hotkey Units Attack / Move Set Rally Clear Rally Stim Lift Burrow / Unburrow Hold Position Unload Unload All Siege / Unsiege Cloack /Decloack Shift Select / Deselect Return Cargo Arm Comsat Scan Lay Mine All spells |
Select Building Hotkey Building Build / Morph / Warp / Evolve Train Cancel Train Hatch Merge Archon Merge Dark Archon Research Upgrade |
JCA also credits 
Lasgo with the idea. Go and keep on analyzing your replays, now on a much deeper level! Go download it now and check it out! JCA just solved the mystery of what many people were wondering. The arm is "the action stored in the replay when you train an interceptor for a carrier, or when you train a Scarab for a Reaver. Unfortunately, it is the same action in the replay." Thanks for the clarification!Links
