Can BLE connection slave latency > 0 allow a connection event to be skipped even if there is data to send?

[VVain.1]

This is the behavior I currently observe.

I Send data at fixed intervals, but if i set slave latency to 1, than from time to time, i will have short periods of misses, the data arrives +- 1 connection event.

If i set slave latency to 0, the data arrives on time all the time. (But then I can't use FLASH).
