A2R: So your research is one more example of the value of "lmgtfy.com".

hehe
Tx A2R
If anyone creates an acceptable solution to improve existing performance, will the SOL engine be updated with that piece of code ?

After reading some of Kroppyer's posts, it seems that we have to make the best of the performance-calculation, just as it is today and update the SOL Client Manual with a lot of tips and tricks.
I can't answer your question regarding a possible update in the performance model. If there are any plans to change the performance model, I would like to offer to help.

As for the guide/manual, there could be a discussion about what should and shouldn't be in the manual, but for now I'd say the manual is there to explain how the game+client works. I think all knowledge about how the game works and most (if not all) of how the client works, should be in the manual.

So, it might be good to explain the performance model in the manual. Problem with this is that it might be very (too) technical.

BUT, explaining how to use the knowledge of how the game works to your advantage should not be part of this manual [My opinion]
This topic is far to extensive, there are complete books written on how to route across the oceans. Of course the performance model is very SOL-specific, and how to use it to your advantage is (as far as I'm aware) not discussed anywhere else than on this forum thread. But that doesn't change my opinion that it's not up to SOL to tell us how we can be faster.

So, explaining the performance model in the manual: yes [my opinion], tips and tricks in the manual: no [my opinion]

I am happy to help in an attempt to explain the performance model in a simple way, without too much maths.

I agree with you that the performance model should be explained in the SOL Manual, not how to use the model.

I'm more concerned of the future SOL virtual sailing program. Have the SOL engine creators made any promises to Sailonline NavSim AB, that they will perform improvement or is it up to SOLers with programming skills to create needed code.

Sorry, SOL is just a game we are playing.
I have to play SOL a lot, hopefully I'll get some skills. Excel is helping me with VMG-calculations.
May I suggest a graphical model for the method of dealing with perf loss, as it would be more rapid to use, and much easier for some of us "less numerate" SOLers.
I have drawn up two suggested graphical layouts, with FICTITIOUS lines, which might be used as a model for such graphs. Unfortunately the "server" does not seem to like them, so I am sending them to RainbowChaser, whose e-mail I know and requesting her to forward them to Kroppyer for his inspection.
If it breaks, it's not strong enough--if it doesn't, it's too heavy.
Rod, you can mail me at (info (nospam) kroppyer.nl)

spinnacer will include a graphical way of showing performance loss. Attached two previews. Might take a while before it's finished.

this one has a cyan line indicating the performance loss when turning from the angle indicated with the gray line, the cyan circle is the 93% line. (It's still a work in progress)

I have sent you my suggested graphical layouts. I would suggest that consideration be given to the idea that the PRINTED GRAPHS
could be placed beside the computer, so that the information need not be entered in a separate 'window' on the computer. I think that I, personally, would find it faster and less confusing......
If it breaks, it's not strong enough--if it doesn't, it's too heavy.
Agree with Rod on this point.
This would be extremely handy for those SOLers who are traveling or have a job/social_event to go to.

IMO, keeping the "casual" skipper in the game is important to SOL in the longer term.

What is a "casual" skipper?
Someone with a life outside of SOL.
We need them!

Rod suggested to make a graph of the formulas, so here you go.

These two graphs should, together the the knowledge that:
> Tacking and gybing results in a performance loss of half the boatspeed in percentages
> Any manoeuvre executed with a performance of below 93% will not cause extra performance loss
> Performance loss is subtracted from current performance*

should give you a fairly accurate approximation of the performance loss for all normal cases.

*) Not true, but reasonable approximation for the usual values. When stacking performance losses (not waiting until you get to 100%), this gets inaccurate.

The distance lost graph becomes inaccurate on high speeds.

________
EDIT: I will update the "distance-lost-graph.png" to make it more readible, and easier to read of the distance lost after a single tack of gybe more easily. If you want to print this, and you are short in paper or ink, I would suggest you wait a day or two (at most) so that you can print the updated version, without wasting paper. Save the trees! ;)


EDIT
New graphs and explanation can be downloaded as pdf here
