about to move into unchartered waters, page-33

I might be getting a bit technical here, but the reason I asked about substantial notices the other day is that I wasn't sure whether SOL had to lodge one each time they went through the 1% level, or whether they were allowed to wait until they had finished a block of buying (e.g. are they able to say for instance "we are in the process of buying 5% of the company over the next month" and can then just lodge one notice at the end of that)?

They only lodged one notice for instance when going from 7% or so to 13%.

Could it be that we just see one notice when they reach 19.95%?
