first note is hacky.
So, offset -25 is what sounds best for everything but the first note. celerih came up with this solution:

Keep offset at -25 and then put the first note on the 1/16th tick after the white tick. This way the first note and the rest of the map should play correctly
edit: other option is to set timing point at 0 offset, place the object and then delete the timing point

current od/hp settings aren't exactly fitting with the spread as the hp is the same on the top 3 diffs (insane, expert & master) despite having a huge difficulty gap between then, & not to mention hard having hp 5 which is problematic, i strongly recommend you to fix them, here's a personal solution:
hard: hp 3-4
insane: hp 4-4.5
expert: hp 4.5-5.2
master: hp 5.2 - 6 (since it's spaced streams i don't think you'd need over 6)
