Well - the only way to push it to work is change acquisition_mask_value to 0
but then there's no need to use most of settings:

also works correctly - so is override really necessary?
And I saw somewhere that if 'acquisition_mask_value' is equal 0, the 
getTitle everytime executes Base_getFunkyTitle. I need to create Title 
once, and change it only when some fields are changed. How to?
