Good Afternoon Jon,
Thanks for your very prompt and comprehensive
response.
I’ll try your suggestion later this week and will
also send mail to RYA on the issue.
Best regards

Hi Dave,
The problem is the NHC2014 algorithm realigns only
the boats that have sailed, which leads to issues
when only part of the fleet sail. The RYA have
specified a minimum of 3 before adjustments are made
but in my opinion it is really an issue if only a
small proportion sail. They have addressed this
issue in the 2015 spec by making all boats realign
after each race, but have created some other issues.
What we need really is the RYA to get the
specification clear and debugged. Perhaps some
emails from users to technical@rya.org.uk
may prompt them!!
As you seem to be aware with the Excel template
(External) mode you can specify the minimum number.
If you experiment with this then you will find that
it really doesn’t work at all if you go below 3
It is already possible to configure the internal to
use a different number of finishers (Although I’ve
not published it previously as the RYA want to
discourage using non standard parameters) To do this
you need to create a file SWHelper.ini and place it
in the same directory as SWHelper.exe
The file should contain
[Parameters]
AdjustP = 0.30
AdjustPX = 0.15
AdjustN = 0.15
AdjustNX = 0.075
SD_Over = 1.50
SD_Under = 1.00
MinFin = 3
You can omit the lines you don't want to change
MinFin is the parameter you want to change in this
case
Let me know how you get on.

Good Afternoon Jon,
Thanks for these replies on NHC and all the work you
put into sailwave.
I brought up the issue of ratings remaining
unchanged if only 2 boats sailed and finished with
you last year. I agree with Malcolm and I can’t find
this in the RYA document anywhere. If the RYA tell
you that 3 boats are needed not sure why they don’t
tell everyone else. It was a contentious issue in my
club last year.
Would if be an option in the NHC tab that when
Internal mode is selected that a minimum number of
boats could also be selected.
best Regards

Hi Malcom,
Would you like to send me your blw file so I can
check it out. Does the column reflect the value in
the rating for the next race? If you have excel and
use external mode is this the same?
It was added later to the instructions

Hi Jon
Thanks for the quick and useful reply.
1. I've downloaded the latest version of
SWHelper.exe and the behaviour is the same. Looking
on the web at published results from other clubs, I
haven’t seen any example where the displayed
NewRating does change from race to race, although
NHC1 does change. Many published results don’t show
this column, so perhaps I should also hide it.
2. Fine
3. I guess it makes sense not to change the ratings
unless at least 3 boats compete, although in the RYA
document “NHC Results Software Calculations 2014” I
didn’t see any mention of that.
