Counterstance test (encompasses JA, Melee Gaiters/+1, and Melee Gaiters +2)
99 mnk/dnc with 5 Counter merits.
Vere//Thew
Ocel+1/Wiglen/Brutal/Aesir
Temple/Melee+2/Dark6%/Pagu
Atheling/Black/Tantra+2/Creek
Target: Orapodium
Kept between 1 and 4 mandies hitting me; never allowed attacks from sides or back.
Atma: Apoc, Mounted Champion, Perfect Attendance
Cruor buffs: HP only (after first two fights)
Test 1: No Melee Gaiters used for Counterstance
Note: 14 hits landed when Counterstance dropped and I didn't notice.
Code:

Player Evasion Evasion % Parry Parry % Counter Counter % Intimidate Intimidate %
Motenten 694 41.14 % 0 0.00 % 497 50.82 % 0 0.00 %
Corrected values: 497 counters out of (497 + 481 - 14) = 964 non-evaded attacks, 51.56%
Confidence interval: 48.40% - 54.70%
Given that we know that accuracy affects counter rate, we can be fairly sure that this is not simply a 50% counter rate. Accounting for accuracy, this is most like a 55% counter rate * 95% = 52.25% effective counter rate.
Given 5 Counter merits, it appears that Counterstance provides a 50% counter rate on its own, and thus 55% with the merits. (Assuming that Counter merits add directly to the Counterstance counter rate; not tested.)
Test 2: Melee Gaiters +1 macro'd in only for JA use. If there's an increase in counter rate, don't need to test wearing them fulltime.
4 hits got through without Counterstance up
Code:

Player Evasion Evasion % Parry Parry % Counter Counter % Intimidate Intimidate %
Motenten 779 43.23 % 0 0.00 % 601 59.56 % 0 0.00 %
Corrected values: 601 counters out of (601 + 408 - 4) = 1005 non-evaded attacks, 59.80%
Confidence interval: 56.74% - 62.79%
Conclusion 1: Gaiters do not have to be worn fulltime to gain the counter bonus. The high end of the confidence range without using the feet is below the low end of the range while using the feet, so it's clear that the bonus was applied.
Factoring accuracy out of the confidence interval range, the raw counter rate should be between 59.73% and 66.09%, which means both 60% (+5%) and 65% (+10%) are possible as the bonus on Melee Gaiters. Another 1000 samples should narrow the confidence interval enough to identify which is the actual value.
Test 2b: Continuing the above parse for another 1000 samples.
Additional corrections:
12 (+4 from first set) hits and 4 counters when counterstance dropped
25 hits when lost target and disengaged (took time to reengage, so a fair number of hits got through; happened twice)
3 counters from accidental PC activation
Code:

Player Evasion Evasion % Parry Parry % Counter Counter % Intimidate Intimidate %
Motenten 1705 44.74 % 0 0.00 % 1204 57.91 % 0 0.00 %
Counters: 1204 - 4 - 3 = 1197
Hits: 875 - 41 = 834
Counter rate: 1197 / (1197+834) = 58.94%
Confidence interval: 56.78% - 61.06%
Factor out 95% acc:
Confidence interval: 59.77% - 64.27%
From this we can exclude +10%. +5% is still possible, but it's at the very edge of the confidence interval range. Best guess is that it's actually +7% or +8%. The observed rate divided by 95% accuracy gives 62.04% as the nominal total counter rate, which would be +7% compared to not using Melee Gaiters. The first 1000 hits gave a value that would result in 62.95% nominal counter rate, or +8%.
Upgraded Melee Gaiters to +2 for third test.
18 hits without counterstance
8 hits disengaged

Motenten 1494 42.19 % 0 0.00 % 1288 63.73 % 0 0.00 %
Hits: 733 - 26 = 707
Counters: 1288
Counter rate: 64.56%
CI: 62.44% - 66.63%
CI/95%: 65.73% - 70.14%
There's definitely an increase. The upper bound of the confidence interval for the +1 test is below the lower bound for this test.
Am guessing the nominal counter rate is between 67% and 69%. Given that the +1 test indicated a value that was likely between 61% and 63%, it could be an additional 4% to 6% (and possibly up to 8%, but that seems quite unlikely).
It's rather difficult to pin down with this sample size (and I'm not up for the massive test that would be necessary to really nail the values), but given the patterns seen in other relic+2 gear I'm going to guess that the Melee Gaiters/Melee Gaiters +1 have an 8% enhancement, and that the Melee Gaiters +2 have a 12% enhancement.
Minor implications:
Counterstance w/Melee Gaiters +2, 5 Merits and level 99 Spharai would reach the counter rate cap of 80%.
