Parachutes, what are Deploy Time and Semi-Time?

[davidpsummers]

The title say sit all. What the heck are the settings "Deploy Time" and "Semi-Time" for?

Where did you find those specific definitions? In the options?

Since you have 274 posts I guess I don't have to explain to you how parachutes work in KSP.

Deploy Time: How long needs the chute to open up fully

Semi : same but for not fully deployed state.

In practical effect: shorter deploy times give you faster deceleration, but at the price of more strain on the ship. Overdo it and you'll snap it in half.

I can at least give you the deployement altitudes, maybe it's helping (I don't know what those times are useful for):

Apparently I should have.

Thanks, I appreciate the replies except for the condescending one. I guess my problem is that I don't see the point. Has anyone ever had anything go wrong because their parachutes open too fast?

Just about everyone that played KSP for more than an hour prior to 1.0 has had problems with chutes opening too fast. They used to be like slamming through a concrete wall when they opened, quite capable of detaching bits of your craft (mostly just if using physics warp).

Semi is the point when the chute is not fully opened/ resembles a sock

Full is when the chute is completely deployed

These matter because decelerated to fast can break things and decelerating to slow and to low = burn up
