In PID terms, this is even simpler yet - just a proportional controller. Only the error between the target and current position are acted upon by a single (proportional) gain:

(targetPosition.x - position.x)0.2 == ekP

A derivative term would be applied to the difference between the previous and current error, usually in order temper the rate of change. D terms can be a proper headache in practice, especially if you have any noise in your system...

Your point on HVAC companies not servicing homeowner-purchased systems is worth underlining.

In our case, we need some duct work to fit a 2-ton Mr. Cool system to our existing ducts. Every licensed HVAC contractor/company we've contacted has refused to touch any part of consumer purchased system, citing liability issues (context: Bay Area, CA).

So much. Open-ended or poorly defined projects can really spiral into attentive dysphoria for me. Productive procrastination – room cleaning and the like – is particularly appealing in that state, just to feel like I'm making progress on something.

Do you mean selling uncovered calls? With a covered call your potential profit is capped, but you aren't exposed to the infinite risk of buying the stock (since you already own it) at a bananas price if it exceeds your strike.

Selling covered calls can be a fine substitute for limit sells if used carefully. Assuming one is comfortable selling at the strike price, the covered call trickles a little profit in the meantime.

As a chronic over-generalizer, you have no idea how much time I've wasted trying to think of the right name for meta-monstrosities.
