How to handle? As of now, we present a default equation for each event type. Other variables might be used, for example price and processTotalForEventType, but they will be conditional both on event type and the existence of price or process (for example).
Should those variables be listed in help text? Or as optional variables in the default equation presentation? Both seem lame: help text either requires cutting and pasting or risks misspellings (and validation of equation entries will be hairy). Optional variables in the default equation risks mistakes from people thinking the default is ok and saving it as-is. (The current default equations will at least compute without error.)
