Ahh yes, I of course mean 2.5 minutes and 1.5 minutes, not paying close attention my mind is elsewhere on more important matters so apologies for that

Anyway all other points remain, you should be far more concerned about the difficulty than by the block spacing being slightly off.
Sorry to disturb you once more about this issue, that does matter to me. Allthough it is slightly out of scope, you did challenge me. If you promise people 1000 NLG each 2,5 minute (150 sec), when you anounce it on github and when you point to a C-Constant that confirms that once upon a time it was your target, but when the outcome is 600 NLG each 2,5 minute during the last two months than there is something wrong. You relieve the market of some 7 Milion NLG each month and you deprive this from your miners. Whatever is the cause, you should be open about the facts.
