I'm aware of my bad reputation concerning my game speed along with the declinations of some coaches thus (which I'd like to change).

For this reason I have to find out how much time my games really take (and, if necessary, work to improve my game speed steadily) and will do the following from now on:

-) I write in the match report of every of my games the game time and will add the note if I needed to use something of the 10 minutes of extra time. Because 4+ minutes turns can bore really. Overtime or exceptionally circumstances like defencelessness (only turn clicking) will be mentioned too to not falsify the data.

-) I will keep a statistic in my profile with the average game time of all my games and the average game time of groups of every 20 games. A progression, if any, will be clear to see.
As a little extra I mention the shortest and the longest games played (a personal hall of (f/sh)ame) :) .

All this helps me hopefully to work on my game speed, adds therefore more fun to those who still play me and may be evidence for refusing coaches to convince themselves, that I made good improvements and maybe reconsider their declinations.
