All opps above the sustained level/frequency are treated as boost, so mark
them accordingly.

I know that we use the terms boost and turbo interchangeably however I
would suggest to avoid confusion that we say "treated as turbo" just
because the variable is called turbo.

Same here, would be better to say "turbo" than boost.

It's simple enough that we can write it as
data.turbo = (freq > sustained_freq_khz*1000) ? true : false;

We can avoid an additional variable and all the other code changes.

Or:

data.turbo = freq > sustained_freq_khz * 1000;
