Quick one if I may as I try and get a feel for WHS.

My HI is 8.4 and round my track my CH is 9 (Slope 125). To get my CH to 8 I have to get my HI to 8.3. The oldest round of my 20 had a score differential of 7.6 - so my next counting round will see that go. The highest SD of my remaining 19 is 10.3. What SD do i have to get next counting round to get the 0.1 I need to get my HI to 8.3?

Assuming I play all my golf at my ’home’ track I‘m trying to understand what I need to do to achieve any goal I set myself on a round by round basis. Is there a quick way of working it out - assuming no PCC adjustments are made.
You need to beat the worst of your best 8 by 1 shot.
Divide that 1 shot by 8, voila, roughly 0.1 lower average.

We can be more precise than that as we know that the 20th score with a differential of 7.6 is going, so the answer is a score differential of 6.6 surely?
Well, from what he actually wrote we don't know what the highest of the current best 8 is.

However, as he has a HI of 8.4, it would be logical that the 7.6 is in the best 8, so yes, 6.6 or better gets a reduction. Well spotted 👍

As per my previous post knowing the other SD's is important as they can sit between a specific range.

When the 7.6 drops off SIL needs to have a new SD of 6.8 to 7.5 to reduce his HI by .1 but 6.8 will guarantee it.

I'm not sure you've done the CH correctly. If the slope is 125, (8.3/113x125=9.2) then by my calculation to get a CH of 8, you would need to have a HI of 7.6.

Ahh, because the average of his current best 8 is 8.35, rounded up to 8.4, and in this instance the total only needs to reduce by 0.1 for the average to drop to 8.34, ie 8.3.

Is this how it works, ie the Differentials are constantly totalled on a rolling basis then divided to one decimal place?

Thanks all for having a go for me. For clarification. 7.6 is one of my best 8 from last 20 but as it is the oldest of my 20 it will be dropped when I next play a counting round. My current best SD is 6.7 and worst is 10.3. Next best SD in the remaining 19 is another 10.3.

Also i have checked and I was mistaken - I have to get my HI down to 7.6 to have a CH of 8. I got the 8.3 from the conversion board now fixed to wall outside of clubhouse - and I read our Blue tees (which we as gents don’t in general use).

Anyway. Question remains around what I have to score to reduce my HI by 0.1 then the additional question is can I get to a HI of 7.6 in one round of golf?

I am coming to the conclusion that there actually isn’t a quick and simple way to work this out in my head...next thing I have to work out is what I have to score to stay at 8.4...and tbh I don’t know that I can be bothered doing this every time before I go out.

But it sounds like a SD of 6.8 will get me 0.1 cut in my HI though I need a fair bit more to get to a HI of 7.6. Though not yet sorted out what sort of single score I’d have to shoot to do that...probably knocking it round in level...🙄😂

Knock it round 2 under, that should do the trick without the need for complicated maths (y)

Bit of self belief, you know you can do it.

For a 0.1 reduction you will simply need to better your 20th score by one stroke. To come down from 8.4 to 7.6, I'd estimate you will need to beat your 20th score by 7 strokes (which would also generate an additional exceptional score reduction of 1.0).

If your 20th score wasn't counting, then you'd need to better your highest counting score by the same.

If you post a screenshot of your scores from the WHS platform, it would be very simple to tell you what you need to score. You can always redact your name.

There does seem to be a lot of overthinking going in.

Register for score, go out, play the best you can - see what the adjustment is.

I did a score on Xmas eve - was +5 thru 3 holes and my playing partners laughing at me for choosing to put a card in.

shot -1 from then on to record a 76. index didn’t change mind, despite it replacing a 77 😂

SILH, I don't get what you don't get 🙂

Your HI is the average of the best 8 Differentials of your last 20.

If you are just about to lose a counting 80, and you replace it with a 72, the total of your best 8 is now 8 shots lower. Divide that by 8 and you've reduced your HI by 1 shot.

If you want to reduce by 0.5, you need to replace a score you're losing by a score 4 shots better.

If you lose a 20th score that's counting and you shoot higher, it will be replaced by the next best in your last 20, which will either be what you've just scored or your previous 9th best that is now your 8th best.

That's ok for a rough estimate, but it's not quite as simple as that due to Course and Slope Ratings, rounding in the various calculations, and values of the other counting differentials.

Did you really go through this sort of process to adjust your handicap pre WHS?

UHS didn't require any such calculation.

Out of interest, earlier this year (lockdown) I designed a simple spreadsheet to easily track/predict WHS indices. It also proved useful in preparing our members for WHS in the absence of England Golf's promised advance preview.

I meant did you target a specific value that you wanted your handicap to be.
