42	GAMES	1982	1982-02-15	08-04	15
43	Sometimes variants are distinct, sometimes not (ex: SF2/CE are separate in PlayMeter, Hyper Fighting is not).	1982	1982-03-15	08-06	15
44	Sometimes cabinet types are distinct (ex: Hang-On sit-in / upright)	1982	1982-04-15	08-08	20
45	Sometimes a game is listed under multiple manufacturers (Crazy Climber Nichibutsu, Crazy Climber Taito in PlayMeter 07-16)	1982	1982-05-01	08-09	21
46	Games are listed from the point of view of the operator: the best are the more lucrative ones, they don't care about the gameplay or whatever.	1982	1982-05-15	08-10	21
47	This means the top games are not necessarily the most played: it also depends on credit price, difficulty, number of players...	1982	1982-06-01	08-11	20
48	Additionnaly, this chart says nothing about games sales: some pretty rare games are high in the charts	1982	1982-06-15	08-12	16
49	This should go without saying, but obviously much more games were being played than what's listed; these are only the top earners.	1982	1982-07-01	08-13	15
50	I try to stick to the written name, but when it changes between issues I keep only one	1982	1982-07-15	08-14	12
51	Sometimes I change the name to help data entry/autocomplete (ex: SSF2T) : avoid using "ctrl+f" to find a game by its title ; prefer using the MAME rom name, or use the "data" tab	1982	1982-08-01	08-15	14
52	Obvious name mistakes are fixed.	1982	1982-08-15	08-16	16
53		1982	1982-09-01	08-17	17
54	MANUFACTURERS	1982	1982-09-15	08-18	13
55	Manufacturers : as listed in the magazine, can change depending on month.	1982	1982-10-01	08-19	15
56	Sometimes a manufacturer changing name is listed under the same name, ex: Bally Sente is listed as Bally Midway. It's just to help me with autocomplete.	1982	1982-10-15	08-20	20
57	When multiple manufacturers (ex: Romstar/Taito) one of them is picked depending on various criterias.	1982	1982-11-01	08-21	17
58	Obvious name mistakes are fixed	1982	1982-12-01	08-23	15
59		1982	1982-12-15	08-24	18
60	ACCURACY	1983	1983-01-15	09-01	19
61	All rely on voluntary polling from operators ; polling numbers are pretty low (90 in first PlayMeter poll, 20-30 in GameMachine), so it's not accurate at all	1983	1983-02-01	09-02	25
62	You can have legitimate concern about the accuracy of what's reported ; for instance, bootlegs, while widely installed, are not listed.	1983	1983-02-15	09-03	21
63	Charts only represent a country: obviously the US and JP charts are different, but in Europe they were probably different for each country too	1983	1983-03-01	09-04	24
64	A detailed letter about polling sample and results problems can be found page 10 of PlayMeter issue 09-01 (1983-01-15)	1983	1983-03-15	09-05	14
65	Polled are probably mainly larger operators and skew the results. Ex: Race Drivin' Panorama is consistently in the top despite only 50 units being produced in the US.	1983	1983-04-01	09-06	16
66	What's accurate to the original listings : games, ranks and ratings (some issues have errors that have been reproduced here)	1983	1983-04-15	09-07	14
67	What's not accurate : exact game names (I can only type "super street fighter 2 turbo" so many times before shortening it to ssf2t), manufacturers	1983	1983-05-01	09-08	17
68		1983	1983-05-15	09-09	16
69	MISC	1983	1983-06-01	09-10	22
70	Page: magazine's page number, may be different than PDF page number	1983	1983-06-15	09-11	16
71	Magazines change formatting and data once in a while so I keep a separate sheet for each formatting	1983	1983-07-01	09-12	17
72	Some issues/scans are missing so the data has gaps.	1983	1983-07-15	09-13	21
73	Sample size is almost never reported. PlayMeter 08-16 has a tiny bit more data. Play-Meter 11-13 says the first poll had a sample size of 95.	1983	1983-08-01	09-14	20
74	Note that ratings are usually printed a month or two after the survey responses are received: PlayMeter of october 1st 1981 has data from august 18	1983	1983-08-15	09-15	21
75		1983	1983-09-01	09-16	16
76	Additional data	1983	1983-10-01	09-18	17
77	Mame is here to normalize games ; unless both a parent and a clone are present on the charts, the parent rom is always used (ex: Zoom 909 is Japanese Buck Rogers)	1983	1983-10-15	09-19	26
78	Some games are not in MAME : their MAME name will start with "notfound-"	1983	1983-11-01	09-20	17
79	Normalized ranking allows to merge different categories in issues separating arcade and street : I took the high number and ignored the other.	1983	1983-11-15	09-21	18
80	Games marked as "duplicate" appear multiple times in the issue ; only the top ranked is kept	1983	1983-12-01	09-22	18

83	Play-Meter equipment polls start at issue 05-11 (june 1979)	1984	1984-01-15	10-02	12
84	Games not marketed anymore are not reported. Sometimes older games still appear when they do particularly well, but this skews the results towards newer games; older ones can still make some money after a few years	1984	1984-02-01	10-03	16
85	Games without enough data are also not reported ; this removes the latest money-maker that are not widely available yet.	1984	1984-02-15	10-04	14
86	Only games reported by a minimum amount of locations are reported; this skews towards bigger, more widely available games.	1984	1984-03-01	10-04	14
87	Issues were monthly up to 1981-06, then bi-monthly.	1984	1984-03-15	10-05	15

97	Only games making above global average weekly gross are reported	1984	1984-08-15	10-15	34
98	Games with < 10% response are not reported	1984	1984-09-01	10-16	36
99	Games with 10-25% response rate but > avg earnings are reported but grouped in a "provisional" category	1984	1984-09-15	10-17	43
100	Starts splitting street and arcade locations at issue 1982-08-15 (08-16)	1984	1984-10-01	10-18	38
