[#2653] Remove uncessary range checks for performance reasons

Browse Source 
Motivation:

I introduced range checks as part of 6c47cc9711 in some places. Unfortunally I also added some where these are not needed and so caused a performance regression.

Modification:

Remove range checks where not needed

Result:

Fixed performance regression.
