Didn't see anything wrong with tuning per cavity history on 07/27/26 when the tuner was put in manual and GMES was lowered by .8 Mv/m. After monitoring for 5 hours, detune angle got greater than -12 degrees and I put the tuner in turbo and Auto and tuner detune angle came back great. I would leave this tuner and cavity #4 tuner in turbo and auto while I monitor. Every time they drop out of RF as a pair, vacuum jumps and takes a few minutes to come down and if the tuners can't tune back faster, CRFP spikes and it drops RF.
