Confusing, isn't it. Kind of like:
- Out of sight, out of mind
- Absence makes the heart grow founder
- He who hesitates is lost
- Patience is a virtue
Both the statements can be true, Carver, but it depends on the the type of transition being employed. A pivot is a great speed minimizing tool that uses a later (post pivot) engagement to avoid the speed gain associated with arcing through the top of a turn. So, comparing a pivot transtion with a later engagement, to an arc to arc with a early engagement, the earlier arc to arc engagement will produce the higher speeds.
Now, it you're talking comparing apples to apples, The more quickly you engage and develop high edge angles when skiing arc to arc, the sharper you will turn, the less time you will spend accelerating down the falline, and the slower your resultant speed will be. So here we have the opposite of the first comparison; earlier results in slower.
Now, the final comparison; arc to arc, to a pushy/washy initiation. Wash = speed dumping. When skiing the same line, the earlier and cleaner you can engage a carve the faster you will go. So, the moral of this situational story is; if you want to ski the same line at a little slower speed, abandon pure arc to arc, throw in a little early turn tail push, and engage the carve a bit later, if at all.
