Speed in measurement plan editor features and speed in start measurement window. My understanding is speed in measurement plan editor features effects inside clearance plane cube and speed in start measurement window effect outside cube.

Speed in start measurement window affects all speeds. Even changing stylus in rack.

Not sure of this would help, but if you have PCM. You can insert this
line of code in a specific feature to slow it down or speed it up.

My understanding is that the speed setting in the start measurement window refers to the speed of travel between features, while the speed in the measurement plan editor and the speeds in the strategy govern the speed within the measurement itself, i.e. within your clearance and retract distances.

I don't run production, I work in a prototype shop with standard job quantities under 5 pieces. So Speed and efficiency aren't a big deal to me.
When I'm done with a program, the very last thing I do is to go into "Measurement Plan Editor Features" and I set my
Travel/Speed to 30
Retract Distance
Clearance Group
Stylus System
Stylus
If I have Free Form scans I change the scanning "Strategy/Speed" of them because the default scan speed is 3mm/s

There's a setting in Plan > Navigation called narrow navigation paths. I can't recall reading anything in the help docs about it, but when it's active the travel speed settings in the feature editor window only take effect within the clearance cube (i.e. approach from the clearance plane and during measurement, but not the retract back to the clearance plane). Outside the cube, the CMM moves at whatever you set it to in the run menu, for automatic stylus changes and etc. I think this behavior is what you described in your initial post.

There are three speeds you should be familiar with when programming Calypso. Babysitting the potentiometer on the control box gets old very quick and sometimes you just aren't fast enough to stop a fatal crash.

The first speed is the speed at which your stylus system travels during navigation. The default is 300mm per second (fast). This speed is only shown in the bottom right of the 'Start Measurement' window (after you hit 'Run'). I suggest when you begin programming, and until you prove out your programs, you keep this at 70mm/s or below.

The second speed you need to be familiar with is the speed of the stylus system before it contacts the part. This is found only in the 'Measurement Plan Editor Features' window, under the 'Travel' drop down menu, then 'Speed'. Think of this speed as the speed after navigation travel but before part contact. The stylus will slow down to this speed beginning at the clearance distance. I have been programming with Calypso for years and I still do not like watching a stylus system rocket into a bore to begin measuring. My personal preference is to set the clearance distance to half an inch, set the clearance distance speed to 10mm/s and let the machine slowly move the probe into the bore to do a measurement.

The third speed is the speed at which the probe scans the feature (assuming you are scanning). This can be found by opening the feature to be measured, clicking on the 'Strategy' button in the top right corner. Then click on your measuring strategy (circle path, polyline, etc). Here you will find the speed for scanning. Use the Zeiss Measuring Cookbook as a starting guide. You will quickly find what works best for your parts.

Your program should look like this when measuring - Stylus system navigates to your feature at navigation speed according to your clearance planes, then moves to measure your feature, slowing down to clearance distance speed when it reaches the clearance distance, contacting the part, scanning at your scan speed, then retracting off the surface to your retract distance where it will speed back up to navigation speed again, off to measure the next feature.

My understanding is that ** is default. Meaning it will grab whatever speed you pick on the Run window.(Image on the right)
If you change the speed of the individual feature to something like 10, it will go slow the moment it switches to that feature in calypso.
That means if you need to change probes to scan that feature with a speed of 10, it will move at 10 after it changes probes all the way from the rack to the part which is VERY slow if you have a long table.

One way to fix that is to create groups. Keep the speed of the group ** and change the speed of the feature.
That way it moves at normal speeds when going around the part but when it gets close to the feature it moves slow.
