[blml] Fwd: Decimal HCP ranges.

IMO, if Tim upgrades 40% of otherwise eligible 11 HCP hands and
downgrades say 20% of 15 HCP hands into the range, he should declare
the decimal range as 11.6-15.2

IMO, down-grades and up-grades that *take hands out of the range*
(for example a downgrade of 10% of 12 HCP hands) should not be
included as part of the range.

In spite numerous libels by BLMLers, we walrus know well that just
because a hand lies within a declared range for a bid does not mean we
must open it with that bid. For example, if we play 12-14 no-trump,
we are under no obligation to open 1N when we hold xx Axx AKQJx xxx

Am I missing something here?
If I describe my method as upgrading half my 11 counts to fall within 
my no trump range then I am playing a 11.5-14 NT. If I describe it as 
downgrading half my 11 counts so that they fall outside my no trump 
range then I am playing an 11-14 NT. Is this what you saying?

No. in both cases the lower limit would be 11.5 :)

Similarly, you could downgrade 40% your 15s so that they lie within 
the range for the bid; or, equivalently, upgrade 60% your 15s so that 
they lie outside the range for the bid; in either case, your upper 
limit would be 15.4.

Having arrived at an 11.5-15.4 HCP range however, if you decide not to 
open specific 12, 13 or 14 HCP hands in the middle of the range, then 
that does *not* affect the range declaration. (Although it affects 
your description of the bid).

I am sure that a simple walrus would have no trouble understanding and 
using Tim's notation, in any of its forms :)

It is just sophisticated BLMLers like David Barton and Jean-Pierre 
Rocafort that envisage complications where none need exist :(
