So I reckon you'd have to AND NotMarca with LegitPress.
And, you're right, we need to latch the Marca signal to damp the oscillations as it gets retranslated.
This only applies if there is such a thing as LegitPress which is doutbtful but may be accurate enough to use in the next generation Bullshit-o-meter, though it would need to be fitted with a "do not use for gambling" warning.
Whilst this would be a neat solution, as you yourself note, it relies on the idea that there is a 'LegitPress' to utilise.
Trying to establish and verify such an entity, if it were to exist, (doubtful) would, IMO, require more processing power than the apparently primitive variant I suggested - I predict my proposal would be about 15% more reliable as well, due to Legit-variance.
