Noseweight (again)

Hello All, absolute newbie with a question regarding nose weight.

I am very happy that my 'maximum' nose-weight is 100kg, this is based on car limitations, towbar max towing capacity, and the 5-7% ratio.  So I am happy with how the weight figure is achieved.

My question is - if it is the 'maximum' nose-weight, does this also mean 'optimum' nose-weight. 

We pack light and to be honest I am struggling to achieve 100kg at the nose with heavy internal items (empty waste tubs, awning, picnic chairs) over the axle where possible.  

Does anyone find that reducing the measured nose-weight below 'maximum' enhances stability and road handling therefore achieving 'optimum' nose-weight. I am aware that every combination of car/caravan will behave slightly differently, but I have a 2.0 Kuga AWD with Alddis Avante. I measure with the Milenco calibrated nose gauge.

I'm a little afraid to play with weights as I'm aware the consequences could be grave, however whenever I read 'do not exceed xxx kg' that's pretty much a warning to keep below that limit where possible.

Many thanks for any experiences or advice you may wish to share.
