Unless you have been a victim of writing the wrong word of a Seed down or the incorrect order of it, you do not know how frustrating and desperate such a mistake can make you feel.
When creating a new Seed, always double check its validity. Not only by writing it down and double checking it with your own eyes. To me, even if the Wallet checks two or three words, it means nothing. There could always be an error and I try to minimize it.
The way I do it is as soon as I write down the Seed, I close the Wallet, then re launch it and use the Restore option. Enter the Seed from the paper I just wrote and go from there.
I wrote words in the wrong order before and at first glance it looked right. Next time I had to restore my Seed from my paper, it said it was wrong. I got desperate for days, until I tried to swap the word with the previous and luckily it did work for me.
Check your Seed twice. Do not be lazy.
That's the kind of trouble you don't think about until it happens to you. Not the same case, but I have had a few problems with wrong passwords that took me several days also to solve, which is also a very frustrating situation.
I always check twice (at least) the digits of the addresses before sending any amount to them, but it is true that I don't give it as much importance as the seed, which is even more important in reality because that's what all the funds in the wallet depend on.
Next time I create a new wallet I'll do it the way the OP suggests: note down the phrase and recover from it. If there is any problem with the recovery, then forget about the seed and create a new one. Much better to realise it before sending any funds, that's clear.
