If it was a CatI approach, the lowest height above the threshold a GA should have been started is 200', not 161, and quite possibly higher depending on the airport lighting and and obstacles. Penetration of the DA wouldn't exceed 30', and I'd expect it to be about 20' if initiated promptly.

I thought this was the correct chart for the approach?

Maybe I'm reading it wrong then?
Ref the post below, and not to sidetrack the thread:
I think I see the difference, it's between AD elevation and THR elevation?

Only half a speed-brake
Chart is correct, OCH 161 feet. There is a marked difference between OCH and DH. In this, thorougly normal and usual case, the lowest DH available to crew is 200' above THR ELEV. See for instance EKCH ILS 22L from AIP, OCH 152 feet.
