Fast Rocket Builds vs. Exosuit Engineer

[WanderingKid]

So, I've been doing a bunch of runs for the fastest rocket builds I can come up with.  While I'm also showing off a little, I'm running into some concerns.  I can Build, fuel, and ready a rocket by Cycle 90 or so.  Here's an example of my last run:

Strapping a telescope to it is not hard, especially if you only need it for a minute or three.  However, the problem is trying to get Exosuit Engineer done faster.

It takes roughly 55-60 cycles even for a supply interest for a dupe to master Exosuit Engineer.  I've had some help opening up the experience system, and it's completely 'time in job' based for supply, as is most of them.  Successful task completion doesn't matter for any exp gained, just how long they're doing the task(s) does.  Additionally, while interest does help for supply jobs, the majority of the experience gained is passive, as active experience is set to VERY_SLOW.  It's not too much later after that you can get your cadet trained and launched (7-10 cycles).  My best speed so far was this run, where I got cadet trained at C116:

Afterwards, you just race to the rocket that's been sitting there for nearly 30 cycles and can finally leave!

While all this waiting time lets you start just playing around and building up a better radar/mining/cooling system for space, the time gate for rockets is not the materials to build it, but trying to get the dupe to get in there!

So, I'm wondering if anyone else has done fast rocket construction and what has been your opinions/engagement of doing so?
