Erm, to an extent, but you are quoting these figures without any context.
When you consider that GLA-WAW only operates 2x weekly whilst FR operate PIK-WAW 3 weekly, then the figures look different. Wizz LF on GLA-WAW in Apr comes out to 68%, whereas presuming that FR operated their 3 weekly schedule as planned then theirs comes out to about 57%. I'm also interested as to why you've apparently chosen to ignore the numbers from the previous month (1st month of Wizz GLA ops) where GLA-WAW was 2324 and PIK was 2086 (possibly <50% LF)?
After 2 months it's too early to draw any conclusions, but I would hardly say the stats indicate stellar performance for FR/PIK.
