The IRS Phish amount just went up

So now I learn by email that my IRS refund is $343.56, thats more than double since last week's $147.59. Both are of course completely fake, the IRS does not notify people about refunds by email.

There is a strange synchronization problem for the attackers. If they all use different refund amounts they create suspicion and their response rate goes down. But some attackers are still using $147.59 which was last years scam amount while others seem to think a change will be more effective.
