Another way of doing it is with the apostrophe, eg. 反応 → han’nou, 万人 → ban’nin. I think it’s a little more consistent and avoids situations where I might accidentally tap n too many times or fail to actuate the key from sloppy typing.
Someone pointed out double check already, but that script also has lightning mode which I consider a fairly big time save. The other thing that saves me a lot of time, but is debated due to disabling interleaving is using 1x1 mode (aka back to back).
It’s not like those things are exclusive. Those unnecessary reviews are also minor frustration. In the grand scheme of things it doesn’t matter, but the natural tendency is to fix problems that cause annoyances. Some people don’t mind a squeaky hinge, others will go insane within five minutes of discovering it. Assuming they do move on to reading or other immersive activities they’ll learn/reinforce those items one way or another.
WK is already an incredible time sink. Adding an extra review’s worth of typing for an individual item doesn’t sound too bad, but in the context of doing the like 140k+ reviews needed to finish WK it’ll add up.
Which reminds me, I really hate that that script is named like that perma associated with undo functionality when it also incorporates mistake delay and lightning mode. I couldn’t live without the latter and the former is something I feel should just be site native functionality.
