Time of Need/Recovery Mastery Out of Sync

The Time of Need node seems to not be functioning properly with the recovery mastery that states "Life Recovery from Regeneration is not applied
Every 4 seconds, Recover 1 Life for every 0.1 Life Recovery per second from Regeneration". This effect only seems to apply once at the start of a map/zone, and then desynchronizes for an extended period of time.

Expected behavior:

0 Sec - Nothing
4 Sec - 100% life regen over 1 second start. Recover 1 life for every .1 Life Recovery per second from Regeneration.
5 Sec - 100% life regen ends
~~
8 Sec - 100% life regen over 1 second start. Recover 1 life for every .1 Life Recovery per second from Regeneration.
9 Sec - 100% life regen ends
~~
12 Sec - 100% life regen over 1 second start. Recover 1 life for every .1 Life Recovery per second from Regeneration.
13 Sec - 100% life regen ends

You would expect to see that every 4 secs, you get 1 sec of regen (which gets converted to flat recovery once right at the start), then 3 seconds of downtime.

Observed behavior (observed at start of an area):

0 Sec - Nothing
4 Sec - 100% life regen over 1 second start. Recover 1 life for every .1 Life Recovery per second from Regeneration.
5 Sec - 100% life regen ends
~~
After this, things get out of sync.
~~
7.9 secs - Recover 1 life for every .1 Life Recovery per second from Regeneration.
8 Sec - 100% life regen over 1 second start.
9 Sec - 100% life regen ends
~~
11.8 sec - Recover 1 life for every .1 Life Recovery per second from Regeneration.
12 Sec - 100% life regen over 1 second start.
13 Sec - 100% life regen ends


This will repeat until it gets out of sync enough for it to loop back around, to look something like this (putting 300 secs as an example, as it takes a while).


300 Sec - 100% life regen over 1 second start.
301 Sec - 100% life regen ends
301.1 sec - Recover 1 life for every .1 Life Recovery per second from Regeneration.
~~
304 Sec - 100% life regen over 1 second start.
305 Sec - 100% life regen over 1 second start. Recover 1 life for every .1 Life Recovery per second from Regeneration.
~~
308 Sec - 100% life regen over 1 second start.
308.9Sec - Recover 1 life for every .1 Life Recovery per second from Regeneration.
309 Sec - 100% life regen over 1 second start.

This repeats until it again gets out of sync.

This seems to be the case for other similar sources of %life regen every 4 seconds (like Surge of Vigour).

It’s still not working!!
