Looks like Gaprindashvili peaked in 1972, at rating 2450 and ranking 148-174.

A brief summary:

Between 1969 and 1979, the Elo rating of Gaprindashvili moved between 2390 and 2450 (peak at 1972)

The rating to rank Nr. 100 of men moved between 2480 and 2500, of which Gaprindashvili fell 30 to 95 points short. Her ranking peaked at 148-174.

In January 1979, Gaprindashvili had lost Woman Champion post to Chiburdanidze - but Gaprindashvili still had the higher rating, 2405 against Chiburdanidze´s 2380.

The 1978 world championship looks convincing. 9 draws, 4 wins for Chiburdanidze, 2 for Gaprindashvili.

So why did Gaprindashvili lose only 20 points and Chiburdanidze win only 40, failing to pass Gaprindashvili?

1980: 1 - Karpov (Champion) 2725; 2 - Tal 2705; 10 - Gheorghiu 2605; 95-100 - Vadasz etc. 2500; 487-518 - Chiburdanidze (Woman Champion) etc. 2405; 655-708 - Gaprindashvili etc. 2375

January 1982: 1 - Karpov (Champion) 2720; 2 - Timman 2655; 10-13 - Larsen etc. 2605; 87-103 - Inkiov etc. 2495; 590-635 - Chiburdanidze (Woman Champion) etc. 2390; 677-721 - Nana Alexandria etc. 2380

July 1986: 1 - Kasparov (Champion) 2740; 2 - Karpov  2705; 10 - Portisch 2605; 94-102 - Flear etc. 2505; 243-264 - Polgar Zsuzsanna etc. 2455;  348-374 - Chiburdanidze (Woman Champion) etc. 2435;

January 1987: 1 - Kasparov (Champion) 2735; 2 - Karpov  2710; 10-11 - Spassky etc. 2605; 73-78 - Chiburdanidze (Woman Champion) etc. 2530; 96-100 - Rodriguez etc. 2515; 134-150 - Polgar Zsuzsanna etc. 2495

Do you think the 100 point rating jump of women between July 1986 and January 1987 was genuine?

How did they perform against Vera Menchik?

Note that if you were to apply the 100 point boost retroactively to Gaprindashvili in 1969-1979, she´d have been in top 100 all that time.
