G'day jjdoom
Glad to see you're into it! Trial and error is certainly part of the process
FWIW, just a couple of really basic, starting point suggestions…
1) Get a DMM from Andy! It'll give you repeatable way points to make changes consistently - otherwise there is no real way of understanding what has worked, and repeating it when it does!
2) But … if you are just getting going, and want a place to start for "go by feel"… this is a really basic 'go to' technique using the Bosch gun, lidded corretto and 350g batch sizes…
• Try starting the roast on 370 fan 2.
Increase the gun by 40° on the gun at 2.5, 5, 7.5 and 10 minutes.
At first crack (make note of the time this happens - should be around 12-13mins) drop the gun back 30° every minute until second crack just begins.
Drop beans. (should happen at around 17-18mins).
If you find these 1C/2C times are much earlier or later - then just change your starting temp to slow things down or speed them up. From what I've found with the Bosch gun, a 10° change in start temp but using the same 'technique' above will be about 1 minute change in overall time length.
Here is one of my 350 profiles for a visual reference… (ignore all the clutter - the red line shows my basic gun inputs…)

Hope that helps!
Matt
And BTW - it might be worth shifting further question or discussion of your results from here to one of these threads or similar - lots of good info for you, and keeps it all contained under one roasting style. It will also help other future corretto roasters to find
Cheers
