I don't know where you are getting 62.55 from. This page suggests Warne's average in India is 43.11:
Bowling records | Test matches | Cricinfo Statsguru | Cricinfo.com
And even that average is inflated a bit due to the lack of support in that legendary 97/98 - he was a one man band. Gavin Robertson was the other spinner, Kasprowicz led the pace bowlers with Adam Dale as support. Warne was quickly worn (:doh) down.
To prove, here's Warne's averages in India:
with McGrath: 6 Tests, 24 wickets @ 38.58
without McGrath ('97/98): 3 Tests, 10 wickets @ 54.00
Still not awesome with McGrath, but a darn sight better than that 97/98 tour indicated. I'll be the first to admit that India is his worst venue - but he wasn't HELLISHLY BAD, like Joe Average cricket fan thinks.
