Clipper87 ,you are wrong, wroot has it right.
Look at this example:
We talk about Win10 Pro here, we have 365 days feature deferral set (and no SAC deferral, because after 1903 it will be no such option/policy) and currently 1803 installed, ok?
Here are (expected) release dates of those versions:
1803(currently installed): 30.4.2018
1809: 13.11.2018 ( deferral 365 means, it can't be installed before 12.11.2019 )
1903: 04.04.2019 (for example; deferral 365 means, it can't be installed before 03.04.2020 ))
1909: 20.10.2019 (for example; deferral 365 means, it can't be installed before 19.10.2020 ))
2003: 01.04.2020 (for example; deferral 365 means, it can't be installed before 30.03.2021 ))
2009: 10.09.2020 (for example; deferral 365 means, it can't be installed before 09.09.2021 ))
So the result is :
- every half year (around april and october) you will be updated to "one year old" release (for example on 3.4.2020 you wil get 1903)
- you will not be able to "skip" versions and install once a year (now you can do this - for example, with SAC and 365 days set you can install 1709 in summer 2018 and then-next summer- when 1809 is out+tested you change policy to no SAC and 180 days and you get 1809; then you set again SAC and 365)
