 ### A maintainable control surface
 
 The effect of modular can be measured in lines of code (LOC). If a model only has a modeling file, we add its LOC count.
-However, if a model has a modular_*.py and a corresponding automatically generated modeling_*/.py, we only count the LOC under the modular file. The modeling code has no maintenance cost as it is strictly dependent on the modular file.

 That gives an "effective LOC" curve: the 𝗺𝗮𝗶𝗻𝘁𝗲𝗻𝗮𝗻𝗰𝗲 𝘀𝘂𝗿𝗳𝗮𝗰𝗲.
