I have been keeping track of several stats for a number of trips during my first year of BOLT ownership. None are really long (200 mi max) but they total 3600 miles. I live in the "Piedmont" (think "foothills") of North Carolina between the coastal plain & the Blue Ridge Mountains. All of this travel was here and in the mountains, up to the top of Grandfather Mt. and its Mile High Swinging Bridge (5280 ft) on two occasions.

For my spreadsheet calculations I took the odometer distance traveled and subtracted the GOM "miles used" (start to end) of a trip. Dividing the "difference miles" by odom miles (x100) gives a percentage regeneration. Frequently the difference will be less than 0, (GOM range will have dropped more than the odometer miles traveled), in this case my equation puts in 1 mile of regen (You know you got SOME!). The GOM range will drop more than the odometer range traveled due to high interstate speeds, cold weather heater use, wind, rain etc. I have come up with an average regen of 7.4%. I did not use L mode as much early on or it might be a bit better. FYI the best I ever got was 38.8% to & from the mountains in very nice weather. Odom distance was 152 miles, GOM only dropped 93 miles.

I wouldn't trust the GOM for any efficiency calculation. I am not sure what the 7.4% regen number means. The energy panel reads out miles traveled and kWh used. As long as you don't first go down hill after a full charge (because it doesn't do negative numbers), you can log the numbers and see the difference in energy used per mile at any point. I live in the Berkeley Hills and know that a 400 ft climb in about a mile costs an extra 1kWhr. But I can make the round trip down and up and still average above 4.5 mile/kWh. This indicates that the regen recovery of energy going down is quite efficient. Probably 75 to 80 %. I have seen a variety of numbers on that kind of regen efficiency.

The main usefulness of the GOM is in telling you whether or not you are going to make it. Once when I had the max defrost on too long, it told me I was in trouble.

The difference between GOM and actual distance traveled has little or nothing to do with regen.

For example, on days off I do a lot of long distance highway trips, with my wife so the heat is on so I get significantly less range than the GOM thinks I will get, this is not a reflection of the regen I am getting... after a weekend of this my GOM says I can get only 160 miles on a HTR charge... then I commute to work at 55 mph or less for the first three days I get more actual miles traveled than the GOM thinks I will get... but I don't get any more regen on my daily commute than I do on my long distance trips.

If you don't know how much regen you are getting then how can you say you don't get "any more" on your daily commute than your long distance trips?
