Simon Willnauer commented on LUCENE-1260:
-----------------------------------------

bq. So, you would have the same problem with DocValues!
hmm, not sure if I understand this correctly. how values are encoded / decoded 
depends on the DocValues implementation which can be customized since it is 
exposed via codec. That means that users of the API always operate on float and 
the encoding and decoding happens inside codec and per field. So encode/decode 
in Sim would be obsolet, right?

> The static span and resolution of the 8 bit norms codec might not fit with 
> all applications. 
> My use case requires that 100f-250f is discretized in 60 bags instead of the 
> default.. 10?
