Taking a look at WB engines: which engine does actually use this piece of information? Especially, does Kingslayer evaluate it? And for what purpose?

Joker used it. The point is that in sudden-death-type games (i.e. increment contributes negligibly) the optimal time allocation is to use a time close to what your opponent uses. Even if in your own judgement he uses twice as much time as is healthy, you should not stick to what you consider optimal yourself. Because it is very dangerous to be out-searched by such a factor, and by the time the opponent will get in time trouble, the game will be decided in his advantage with plenty of (now useless) time left on your own clock. So you better not think, say, less than 90% of what he thinks. (E.g. target time = 0.1*optimal time use + 0.9*average opponent time use).

In case the opponent thinks faster than you, it is also very dangerous to let the time he has left on his clock ever become a significant factor larger than yours. If he thinks just 10% faster, near the ed of a long game he could have, say 4 times as much time left as you. (E.g. i a 5+0 game, he has left 40 sec after 40 moves, and you only 10 sec.) You will be badly outsearched, and probably lose. You could have prevented that by having played just 10% faster.
