# Talk:Shatter Skill Recharge Rate

## Notes[edit]

I believe the bug note (now removed) on recharge rate is erroneous and based on a misinterpretation of what recharge *rate* means (i.e. frequency, not period). The actual recharge time is consistent with an increase in recharge rate which is *not the same as reduction in recharge time*. My mesmer at 15% Shredding recharge rate reduces a 60 second recharge to 52 seconds and 60 / (1 + 0.15) = 52.17%. This is roughly 87% of the recharge reduction predicted by the formula 60 * (1 - 0.15), but this latter calculation is providing a 15% reduction in recharge time which is actually a 17.64% increase in how often the skill can be used. At 30% shredding recharge rate, the effect of the rate/frequency adjustment would be the noted 77% (.76923) of the recharge-time/period adjustment.

The use of frequency adjustments applied to something we normally measure by period is confusing but a much saner, fairer mechanic. Increasing rate applies a linear increase in benefit, while reducing period would actually apply an exponential increase and only allow a much narrower range of sane values. Just consider a 100% boost:

If rate actually meant reduction in recharge time, we'd be reducing that time by 100% effectively eliminating any recharge at all and allowing a virtually infinite rate of usage. But following the actual definition of rate we'd expect a reduction only enabling use twice as often in a given period of time. And sure enough, 60s / (1 + 1.0) = 30s meaning we can use a skill +100% as much. --HonoredMule 19:48, 25 January 2013 (UTC)
