DeltaV calculator for SFS 1.35

Chances are, no one uses 1.35 anymore except me but I wanted to share this as a resource for anyone curious.
For single stages its margin of error is 40m/s. For two stages the margin is 70-ish m/s, not sure really. Tell me if you find anything thats wrong with it, or if my math is bad. :)
Instructions are in the spreadsheet.

Also, you could use it for other versions of SFS but you need to change the values of each part.

Visually not a bad effort.

You'll be surprised, there are quite a few people here that play 1.35 still

The sheet is locked for editing though.

Oh, this is interesting. And don’t think you are the only one. I only use 1.35 too, and there are several people who still use it too. 1.35 is the superior update.

Playing a space game on a tiny phone screen is not for me, especially with the imprecision of a fat finger.
I feel your pain. But what made me move to 1.35 is all the bugs in 1.5 and the constant crashes. I could barely play it, it crashed every 5 minutes. 1.35 I can play it with 8 GB or RAM, so no lag even near immense stuff.

That's some very detailed stuff, there's obviously a lot of work that went into it.
There are still some 1.35 players here and there, I'm sure they will appreciate :)

That'll be the specific impulse is off slightly. There shouldn't be a margin if it's maths. Aside from that, the calculations look sound and the cells all point to the right places.
The only bug I can see is that if there isn't a number (as in, there isn't a zero etc) in all the engines section for the stages, the delta velocity does something nuts

You are 100% right.

Thanks! Do you know how I can reduce the margin?

Ok, thanks again! :) I'll see what I can do about that.

The only time I've experienced lag in 1.35 is when I was orbiting Mercury with a space station and every time I got close to it with another craft (like a lander), my frames would drop. Also when I first got to mercury with that station, I got to ~ 5 meters off the ground while going at orbital speeds, the game didn't like that.

Does it work with Android or iOS

It's a Google spreadsheet.
It works anywhere Google works.

"Google Sheets is available as a web application [for Windows, MacOS, Linux], mobile app for: Android, IOS, Windows, BlackBerry OS and as a desktop application on Google's Chrome OS. The app is compatible with Microsoft Excel file formats.[2]"

Additionally it's only valid for SFS version 1.35 as the title says.
As the post you quoted explains, you have to change the values for other versions.
Which is a tedious task compared to looking at a deltaV chart for 1.5:
