There are some nice statistics at https://metrics.torproject.org about node types. As of 9/24/14 the total advertized bandwidth for guards was 8.6Gbps, exits 4Gbps, and middles 2Gbps. If you want to distribute tips proportionally, based upon those numbers guards should get less than a quarter share and exits a half share. It is very difficult to run a fast stable middle because as soon as you accomplish that it becomes eligible for the guard flag and no longer gets used as a middle.
Note that exits and guards also get used for the middle position, and that there are nodes which are exits and guards at the same time.
