obviously there is a big difference by using:
----------------------------
lock screen for visual effect
go next
unlock screen...
----------------------------
And:
----------------------------
 visual effect ...
 go to next card
----------------------------
Using the latter I get this in the msg:
1683043997883
1683043998101

Not the full 300 millisecs difference as exspected by the effectrate, but more than in my first test.

Someone knowing please chime in! :-)


Best

Klaus
