Micronucleus V2.02 firmware BOOTLOADER_ADDRESS

[DannyBoy]

I am trying to create jumper firmware V2.02.
I was studying configuration of releases in GitHub repository (https://github.com/micronucleus/micronucleus/blob/master/firmware/configuration/t85_default/Makefile.inc),
trying to learn how to calculate bootloader address.
It seems to me that the address for default t85 firmware starts one page (64B) too early.
Bootloader address in the configuration is 1980, but i got 19C0 ("data" size was 1592).
Am I doing something wrong?
