What bugs me more than English spelling mistakes is:
1. Unusual way the readings are transcribed.
2. Using kanji that are not in the book.

I address the first issue with the following format:
先生に聞けばよかった。
せんせい・に・き・けばよかった。

For 2., I put characters that are actually in the book. I understand that this limits number of the used kanji for, at least, the Basic part but I'm not really concerned about it. Also, I think that sometimes the use of kanji in the original deck is unnatural, as in, a Japanese person would not use those.

it is still an awesome deck.

Yes, no question about that. If by any chance the person who did that deck can read this, I'd like to thank them for sharing this deck with others.

there were some actual grammatical mistakes though not many. The person that wrote this admits it on Anki, though. I am not good with computers - how could you do what you suggested?

You shouldn't even be paying that much attention to the English.

I'll try to do it Monday at the latest.  My Mac doesn't have spell installed.  Sigh!

It looks fine to me too. I think he is referring to the English again because it might be more accurate to say "He survived the traffic accident" rather than "was almost killed".

@netsplitter and blackbrich The Japanese verb was active not passive: He almost died because of a car accident

I decided to look this entry up. I went through and spent about 2 days actually tagging where each sentence comes from in the books.

According to the entry in the Intermediate, this entry is exactly right. The person that made the deck did not screw up.

Intermediate book, Appendix 2 page 637

Note: In this sentence ~そこなう has a meaning of "almost"
彼は通交事故で死に損なった. He was almost killed in a traffic accident.

is this a mistake? ー 松本[まつもと]さんと 池田[いけだ]さんと 清水[しみず]さんの 中[なか]で 誰[だれ]が 一番[いちばん] 出来[でき]ますか。
ー 池田[いけだ]さんです。
ーAmong Mr. Matsumoto, Mr. Ikeda and Mr. Shimizu, who is the best student?
ーMr. Ikeda is.

Its correct. There's a note that "best student" (lit. can do best?).
