Unless it's changed in the last couple of years I thought Dancing with the Stars used a 50:50 split for the voting, although I think combined them differently to Strictly.

So many of these 50:50 shows don't actually explain how the votes are combined (on screen at least), but my understanding is Strictly use a ranking system, with the rankings combined to give the final score (and I think usually the public vote breaking any tie) whilse Dancing with the Stars combined percentages - so the judges scores for all contestants added together and the couples judges score effectively became a percentage of the overall judges scores, which is then added to the percentage of votes they get.
I preferred the internet when it had a sense of humour.
