Logic behind score doubled!

There must be some logic behind a recent score query  - can you please advise.

4H* making 10 scores 790

3H* making 10 scores 930

2H* making 10 scores 1070

1H* making 10 scores 760

So the game contract doubled scores the second least points!

    Most beginners text books will explain how bridge scores are calculated. It is worth spending a little time to understand the scoring as you can then make the best decisions.

    You state "So the game contract doubled scores the second least points". Well no ... because both 3H doubled making and 2H doubled making are also a game contracts. (For 3H the tricks bid and made score 90 X 2 =180 and for 2H the tricks bid and made score 60 X 2 = 120 in each case this is greater than 100). Note that 1H doubled making is not a game contract (30 X 2 = 60 which is less than 100).

    The scores for each contract are calculated as follows:

    4H* making 10 (Vulnerable)
    Tricks bid and made = (120 X 2) = 240
    Game bonus = 500
    Insult = 50
    Total 790

    3H* making 10 (Vulnerable)
    Tricks bid and made = (90 X 2) = 180
    Over-trick = (200 X 1) = 200
    Game bonus = 500
    Insult = 50
    Total 930

    2H* making 10 (Vulnerable)
    Tricks bid and made = (60 X 2) = 120
    Over-tricks = (200 X 2) = 400
    Game bonus = 500
    Insult = 50
    Total 1,070

    1H* making 10 (Vulnerable)
    Tricks bid and made = (30 X 2) = 60
    Over-tricks = (200 X 3) = 600
    Part Score bonus = 50
    Insult = 50
    Total 760

    As can be seen, the reason that 3H* and 2H* score highly is that vulnerable doubled over-tricks are worth 200 per trick.

    Corollary:
    As can be seen, it is expensive to double the opponents into game. Doubling 2H or 3H is risky and you need to be confident of defeating the opponents. Doubling 2D or 1H is safer because you haven't doubled the opponents into game. (although 1H redoubled would be game! - a whole different discussion)!.
