Hello Gareth,
How long is a peice of string?
If you have the perfect growing conditions and the montana is healthy it can put on 20ft or more of growth in a year.
Most of the more vigorous types can reach 20-30ft in height and the overall amount of growth will increase exponentially each year depending again on the growing conditions - soil, nutrients, weather, position etc.
With unfavourable conditions the growth will become less vigorous with the extremes causing stunted growth and fewer if any flowers.
After a few years of being left to grow unpruned it will quickly become a mass of growth with green leaves on the top and a woody mass underneath. Like most type 1 pruning group clematis they should be pruned just after flowering to keep them within their alloted space.
At the end of the day the plants performance can depend more on you than the plant itself, although some clematis need less care than others.
