While the sample size of this test is rather small, it does however have some useful points such as what appears to be a few
near maximum range hits. Some additional pros about this test are that the tester listed his weaponskill, spec, weapons used
and target armor. The target is not realm rank 5 and is also using an af buff, and with these factors it can probably be safeuly
assumed that the af on the target is 595. One unfortunate thing is that the tester failed to mention whether or not the realm
had any relics at the time, assuming that relics may affect all melee and ranged damage. I believe that the observed max for
506 damage indicates that perhaps hib had at least 1 other realm's str relic at the time.
This tester is attacking with lower weaponskill, and the damage appears to be measurably lower than Slitz's. The maxes are
149 points in difference between predicted 467 and slit's predicted 616 along with a 104 difference between the min damages
of 332 and 436 respectively. QuaiWaldsterben and Slitz are also similarly specced where both have 53 combined spec into bow,
although Slitz is a higher realm rank and gains slightly more weaponskill per stat point due to the way ws calculates plus
skill bonuses with stats. The chief difference between the two are the dex buffs which allows Slitz to gain much more weaponskill.
The difference in weaponskill between the two players is probably around 429. Slitz is assumed to have around 1911 weaponskill.
This gives Slitz an effective 2325% damage bonus which is mirrored in the disparity between the damage of the two testers;
467 is roughly 75% 616, thus making the difference around 25%.

QuaiWaldsterben Test
Testing Player Crafted weapons were as follows
duskwood great recurve bow
16.5 dps (16.2 effective dps)
5.4 Speed
100% quality
Determining damage cap
Damage Cap = EDPS * SPD * 3 * (1 + (SPD – 2) * .03) * (1.1 + (0.005 x spec) )
16.2 x 5.4 x 3 x 1.102 x 1.365 = 394
394 x 0.85 = 334 using 15% light damage arrows
394 x 1.0 = 394 using normal arrows
394 x 1.25 = 492 using 25% bonus broadhead arrows
Determining base damage range 
EDPS * (your WS/target AF) * (1absorb) * (1base resists) * (1RA resists) * slow weap bonus * SPD * 2h weapon bonus * Arrow
Bonus
2h weapon bonus = 1.1 + (0.005 x spec)
SLow Weapon bonus = 1 + ( (spd  2) x 0.03)
16.2 x (1482 / 595) x 1.102 x 5.4 x 1.365
16.2 x 2.4907563025210084033613445378151 x 8.122842 = 327.75872247529411764705882352941
