That is a good question as that combination of ratings is likely quite rare. So as a result unfortunately I have no answer for you. Sorry.
As far as why your Daily rating is your highest, well that is easier to answer as that is the case with myself. The answer of course is you, like myself, simply play better when taking your time.
One way you can think of ratings is like currency. One dollar in the United States is worth about 100 yen in Japan. Just because 100 is a larger number than 1 doesn't mean it has more value. Similarly a 1000 daily rating is not necessarily better than a 800 rapid rating (just an example).
Ratings don't measure an absolute value like height or how fast you run, they measure your performance relative to others on the same website in the same time control. So you can't directly compare ratings across time controls. For lower rated players it's very common to have a daily rating higher than the live ratings.
I always wonder that. Most of my ratings are 400, (around 400), but my bullet and daily are way higher. My Bullet is 700 area, with my Daily being 850+. Why is this?
