Running strategies on the minute

[susitronix]

Hi Richard
I tryed with
22days * 24h = 528h * 60 = 31680 Minutes
When i change the Backtest Time by ONLY one minute i get this:

00:00=20%
00:01=30%
00:02=8%
00:03=6%
00:04=20.8%
00:05=30.8%
00:06=54,5%
00:07=4.3%
00:08=5.3%
00:09=19.8%

Hmm... How does theese Backtest Results change by that much ?!?!!
