RE: Getting off and back on 'the line'; size
Cappaj1, here in the States Sportsman has 2 "out of the box" excursions and as Arch points out you can do any maneuver you need to get back in position. It's true that you should always strive to maintain the line, but that's going to take a while.
Also, be aware that you can use the free turnarounds to adjust the size of the box. The second segment of the Sportsman pattern (two point roll, half cuban, cobra without rolls, immelman, 45 degree downline on center) gets pretty rushed if you're in too close. If you use your turnaround to move out the box gets bigger. The third set of manuevers isn't so compressed, so you can move in a little to where you can see them better.
Even Intermediate has a chance to correct your line. The humpty bump with options can be flown to move you in, out, or to maintain the same line without losing points.
