Not as objective as you think.
Case in point, I achieved the house high at Underground Retrocade (West Dundee, IL) on Frenzy with slightly more than 1 million about a year ago. Stats from that game:
Score: 1,006,802
Got to one million points in 7 hours and 35 minutes (132,000 points per hour)
At about 500,000, I got to 90 extra lives and dealt with the ROM issue for the first time
Took three 5 minute breaks and several 1 minute breaks
With the breaks, Kept my extra lives in the 45-75 range
Killed off the rest of my lives after 1 million with 56 remaining
A friend of mine later beat the score with 1,135,757 but ran out of lives, had no breaks, and never got to 20 extra lives.
He would agree I am the better Frenzy player, but he has the high score... SCOREBOARD. The burden is on me to take it back.
