Initial Height Skip (IHS) not functioning properly

I've noticed when cutting that IHS does not seem to work as intended. Sometimes it will skip the probing routine, but most of the time it does not. I believe it has something to do with the state of the THC. Most of my cuts (artwork) are small and the THC never kicks (enabled, but inactive) in due to velocity anti-dive. IHS does not seem to work when moving between these types of cuts. If a cut is larger and has straighter sections where the THC would actually be active, then it seems like IHS settings are considered between the next cut.

Per the QtPlasmac docs, IHS should function as such:
If I run a program with the torch disabled (dry run), it will properly IHS based on the distance set on my parameters tab, so I know that this has the ability to work. When I run the same program with torch enabled, it does not IHS.

My test program is a grid of holes. If THC is enabled, then it will not IHS between the holes. As soon as I uncheck the THC enable button, it skips probing between holes. My understanding is that with THC enabled (my default state), it should check the distance between the end of the last cut and the current probe position. Even though the THC is enabled but does not activate due to the velocity anti-dive feature, I feel like IHS should still operate as it does with THC disabled.

Test program and machine configuration are attached. I am currently running QtPlasmac version 1.223.186

I am not helping, just awoiding confusion: IHS is not "initial height skip", it is "initial height sense".

If the THC was not active at the end of a cut then IHS skip in THC mode will not operate, that is a slight documentation error.
This statement: Should probably be changed to:
EDIT:
On further reading, I think this: Should be changed to :

If the THC is disabled or if THC is enabled and not activated then the IHS skip will occur if the start of the cut is less than Skip IHS distance from the last successful probe.

This logic makes sense to me. It doesn't currently work this way though, does it? Like you said earlier, if THC is enabled but not active at the end of the cut, IHS skip will not function. It should (in theory) default back to the last successful probe in this case.

So long as you have a large enough Skip IHS distance it will work.

Yeah, it is bad enough on a PC, I rarely reply on a mobile and if I do it is usually without quotes.

Running the test program attached to the first post with a Skip IHS Distance = 3 (inches) does not prevent it from probing every single time. The grid pattern is 0.150" diameter holes 0.300" on center (pierce location delta). The hole pattern is only 1.05" x 1.20" in size so they should all be within the 3.00" IHS Skip distance
