Timecode offset issue

Last shoot I noticed a timecode difference between the denecke timecode slate and the recorded signal. The cam was a fs700 with 4K raw out to the 7Q+. The recording was set to 4k to HD in prores 422. The timecode was fed into the LTC in from the 7Q+ (Due to the lack of tc in on the fs700). However the timecode was like 2 frames off (late). In post they are now struggling with audio to offset it manually. Very unprofessional as there was a lot of effort put into the syncing on set! A F3 camera used on the same dualcam shots was deadsync. On that camera the tc was fed through te tc in from the camera and the outboard 7Q+ got its tc embedded in the sdi signal from the output of the F3camera.
I suspect the combi 4k raw and processing in the 7Q gives an unwanted latency and this should be compensated. With the upcoming fs5 and other similar cams used with the 7Q this will keep giving issues in the future.
I think it will be necessary to have the possibility in the 7Q to give an offset to a tc along with the recorded videosignal. Or even better: the 7Q knows and corrects the timecode all by itself based on thegiven cam and rec.mode as this will be a constante
Could this be implanted in the next firmware?
