Hmmmm .... Yes and no and hhhmmm.
When you make your own custom pellet og slug setting like as an example Zan 20 gr slugs.
You need to prepare to get three minimum 3 slug speeds. This is the maximum speed you can shoot them. The lowest interesting speed you will shoot the slug and minimum one speed in the middle of the minimum or maximum.
1. I set the required Pressure - (In my DW without the ultrafire valve I will need 195 bar to get even close to the max. speed)
2. Then i in advanced mode test shoot and find a Dwell time (or pulse value) together with voltage to get the maximum speed i can get.
Write down the achieved Speed - Pulse and Voltage.
Then I figure there is probably no idea in testing lower as 750 fps with 20 gr slugs.
3 I test shoot again in advance and find a Pulse / Voltage combination that is close to 750 fps.
Write all numbers down.
4 I test shoot the to find 3 to 10 speeds in between the min and maximum speeds.
For all these speeds I write down the Pulse / voltage.
5 Then I connect the rifle to the Daystate programmer and load the current settings.
Go to the factory Tab and under caliber i select .177 and 23" barrel.
Then I add now a new setting called "ZAN 20 gr."
6 I now select insert rows - I choose as example 10 rows. (The minimum for the automatic to work are 3 rows)
7 In these rows - I enter the data I collected from the test shooting starting by the Maximum speed at the top.
You can always delete. add rows before and after a row.
8 You will have to enter Actual pressure (The pressure you used when test shooting) also Optimal pressure and minimum pressure. Minimum pressure i guess is where the pressure is too low to reach the speed so it is more testing or a guess.
Optimal pressure is like for a mechanical rifle the the pressure for a speed where you balance accuracy and air consumption. like a little above the lowest pressure where you can get the wanted speed.
9 When all these informations are entered you can save your new setting to the rifle by pressing write,
Save your new rifle setting as a file with a revision note.
10 now you can take you rifle to the shooting range and start shooting with the Zan 20 gr. settings in factory mode.
Chose any speed within your minimum and maximum tested speed like 880 fps. Shoot 3 to 4 shots and its a "home run"
Now if you chose any speed you did not test in your chart like 770 fps, the rifle will calculate and guess the settings based on the closest lower and higher speed.
When it shoots it corrects itself until another "home run"
When you continue to shoot more and it shoots 4 shots with a maximum variation of +/- 4 fps - It will add a line in your table with the reached settings.
The new added line in your settings will look like the ones you made from scratch with Pressure, Opt. Press. Min Press. Pulse, and Voltage and it will be saved under your custom made setting ZAN 20. You can tell the rows added by your rifle since they have a "Target" symbol on the tabs row number.
This means that if you chose the same speed next time it will be correct from the first shot. More rows with collected data will be added if you change speeds. Choosing another speed makes it do new corrections until the speed is reached by itself - just as shown in the videos.
So to your multi question - if i change any parameters it will correct itself.
Yes but then if using the same like 13.42 and now shoots JSB 10.34 gr. pellets it starts correcting for all settings every time. In my head it is just a mess.
If you have dedicated settings for each projectiles, it remembers all stored settings and will be ready from first shot.
I will explain in the video too - But now the chickens are out - Its not that difficult - and I still do not know why the Daystate shipped without at least the 20-30 most used slugs and pellets in each caliber.
Best regards from Denmark.
Soren and I will show how this is done in a video shortly - be patient

I don’t know.
