Amount of Locklosses per day and percentage of ETM GLITCH Locklosses has not significantly increased
Between Dec 2024 and Feb 2025, 20% of our Observe locklosses were tagged ETM_GLITCH, see 82609.
Since then we've roughly had the same amount of OBSERVE locklosses per day, and the same percentage of ETM_GLICH locklossses.
The amount of locklosses per day in the last 10 days is slightly increased, but not much.
- 1st March - 1st April (32 days) 14/75 (2.3 LL/day) = 19% ETM_GLITCH
- 11th - 29th June (18 days): 9/42 (2.3 LL/day) = 22% ETM_GLITCH
- 1st to 24th July (24 days): 13/60 (2.5 LL/day) = 22% ETM_GLITCH
Looking just in the last 10 days where we feel we've been having more locklosses:
- July 14th to 24th (10 days): 6/29 (2.9 LL/day) = 21% ETM_GLITCH
Here's a visual look at all locklosses versus ETMX glitch locklosses throughout the run
