I believe that even if the file increment is smaller than the extent NEXT, it will make multiple increments to fulfill the extent NEXT requirement. Thus, eg, if the file is ... AUTOEXTEND ON NEXT 64K .. (64K seems to have been the default, if you don't specify NEXT -- this is from memory), and the table/index NEXT is 1M, then the file will still extend by 1MB (ie 16 increments of 64K).
However, : I can't test this right now. I am quite sure that is how it works ... though.

yes... although you might care to test what happens if your increment value is smaller than the next extent size of a table that grows to subsequently trigger an autoextend...I think (haven't tested) that your increment value needs to be large enough to satisfy in one extending operation the size of the extent requested by the table growth... I'd test it here, but my systems are tied up.
