No penalty at all until after you have 5XP, remember that we are using integers, so fractions don't exist. 4/5 = 0 in computer language here. 5/5 through 9/5 = 1, etc. Thus without the +1 you are dividing by 0 for the first 5 XP points and that causes computers to blow up and eat Cheetos.
And as Vehem said, you will gain more XP as a base once this is active than you do now, so technically you still get quicker XP for the first 5, and eventually it works down to about what it gives you now (not sure what the current rate is so can't say WHEN it matches current precisely).
Danger range is a funky thing to deal with because you are just telling the tile "Look out!" and not "That guy 2 squares left and 1 square down is a PITA, go hit him" So if you make the range too large, units are always freaked out so it does you no good (it's like announcing every deer you ever see while riding passenger with someone by shout "Oh my God! A deer!" when you finally see one sitting in the middle of the road and attempt to warn him to swerve, he thinks you are just pointing out yet another one on the side of the road so far out he can't even tell what it is)
