I still have no idea what you are trying to achieve, but, if you want to find some number of equally spaced points on the perimeter of an ellipse, it requires calculus/integration.
In my code, I use one of Ramanujan's approximation functions to get satisfactory results for ring/pendant design.

Given the mention of the Fibonacci gauge, I'm assuming you mean 'draw' as in pencil an paper. Depends on how exact you want to be. There are a variety of technical drawing tools that can help like a French curve and a flexible ruler. There are also templates of various sizes that can be used. I think someone already mentioned that two thumb tacks and a loop of string will also give you an ellipse. They can also be constructed with a compass using four compass points constructing each arc independently and joining them. You might want to search for "technical drawing tools" to get a better idea of your options,

With Windows 11 around the corner, I am pondering whether I should do a clean install or not, when it arrives. I kind of enjoy doing a clean install, but at the moment I have so much stuff on my desktop that it may take the better part of a day.
What are other members planning to do? Maybe this is a topic for a new survey?

My way of upgrading Windows is to save up for a new PC.
One usually needs the new hardware anyway.

Yes. At a stretch I can maybe afford a new drive for my current machine to go with the new Windows!

When VMs are updated to support it, you might try it out for free by installing a trial edition in a VM (e.g. VMware player, which is free for non-commercial use). This wouldn't give you feel for its true speed, but everything else should work like normal.
That's what I did before migrating to Windows 10.

My inclination will be to go with a clean install. My current machine is running the manufacturer image it came with 18 months ago.
This of course assumes that it meets the hardware requirements for Windows 11  .

You can test online for this. However, such a relatively new machine will almost certainly meet the requirements.

My desktop probably won't meet the requirements, so I'll probably stick with 10.
The Surface is new enough it should meet 'em - so I'll maybe upgrade that and see if it's worth the extra cost of an upgraded desktop.

I'm planning on doing an upgrading, like you I have a ton of stuff on my PC and it would take forever to do a clean install.

I prefer clean installs as they don't have any registry crapola hanging around.

I'd go with a clean install on a new disk over an upgrade just in case anything goes wrong.

Makes sense, but my systems disk is a NVMe M.2 that plugs directly into the PCIe bus, making it very fast, but it complicates matters to replace the disk to some extent. However, it is something to consider!

I just bought my new PC a couple of months ago, but I am not really sure if I will go to 11 at the beginning.
I don't know why, but I am expecting even more problems than with windows 10 at the beginning, so I will wait for "Service Pack 1".

IMHO the (extra) time spend doing a clean install will save you years of heartache down the road.

I'll worry about Windows11 upgrade about a year from now. Most of the bugs should have been fixed by then.
Also, I have too many software tools that I am using to re-install them and not that much time.

I won't reinstall from scratch. Windows has not needed clean reinstalls for quite a while now and the last time I had to do one, was after running a preview Win10.
I am willing to bet, I'll have to reinstall the graphics driver (gamer here), but otherwise, there's no reason.
That AFAIK depends on how you treat your Windows though. I am willing to bet, if you're frequently trying out (potentially ill-intended) software, a clean reinstall may be in order. My above paragraph should start with using Only.Install.What.Really.Need;

Upgrade. I've been doing upgrades (to new Windows versions) without issue for over a decade now. And I've been on the Dev insiders channel (so a Windows upgrade every week) for about four years - no issues.
In fact, I've been running Windows 11 since June/July - whenever the first Insiders build came out. It's fine. Some features I like (Snap Layouts - right-click on the Maximize button & get a selection of window snap layouts), some I don't (the new, smaller Windows Explorer context menu sucks hugely - although that might improve as apps adopt the new Windows 11 way of adding context menu items).

Think about it this way -- the developers and testers who work on Windows, at MS, clean re-install almost every day.
There is some long-haul testing done.. and dogfooding on home PCs. (And the Windows Insider program is a great extension of that.)
But apart from that, there is almost no real-world testing of the OS upgrade path. And whatever bugs are found, are almost impossible to reproduce, by their very nature (unless you had presence of mind to do a snapshot backup before upgrading).
I fear the OS upgrade path. (source: I worked for Windows division of MS for many years)
To be fair though, the OS upgrade team must have one of the toughest jobs in all of software engineering -- it's actually amazing to me that it works as well as it does, for so many.
So, the path of virtue is probably to do both..
a) do the upgrade, and report any bugs or issues you encounter.. then
b) clean re-install, a few days later

Do you ever find using the alias "float" inhibits your coding iife ?
Does it bother you when people whisper behind your back: "Impostor ! Just a midget Double hiding behind a pompous moniker."
Does having to say, in a loud voice: "I implement IEEE 754 just like Double" trouble you ... given you consider Double your kind of "older brother" ... and, your natural inclination is to defend Double when they mistakenly diss him by claiming you are superior ?
Do you despise the corporate types who sneer at you (and Double), likening both of you to "lickspittles from the base 2 gulag not worthy of entering a Decimal's presence" ?
I am here to to tell you that you are not alone, even if you are Single.
Sorry I can't be here to help lead Us forward, but, as you know, my simple proposal to rename the alias "float" to "Float4," and give "Double" an alias, "Float8" ... resulted in credible death threats to me, as well as a vicious campaign of fake-news slanders ... I must remain in hiding, in mufti.
Hans Passat on IEEE 754 (StackOverFlow):Quote: It is however a half-baked standard, it only specifies the bit interpretation but does not demand a physical representation. The RFC is infected with Unix preferences from the previous century, like all networking standards are, byte order is big-endian.
