Update KServe stats to include KFServing

[yuzisun]

According to original survey results slide 23 33.3% of users are on KFServing and 48.3% of users are on KServe, KServe/KFServing is basically the same component so when talking about stats we should really combine them.

@yuzisun @annajung one related note, I did a quick search on the answers in the question. 1st on kfserving, which had 50 selections, and then on kfserving;kserve, which had 28, kserve had 78. I believe this may mean that 28 are using both (kfserving and kserve). If we add kserve and kfserving (78+50) and subtract the 28 (the people that use both), we get 100. I think this means the combine % using kfserving or kserve would be 100 / 151 or 66%. Does that sound correct?

Thanks @jbottum for checking for double responses. That makes sense! I went ahead and checked the raw data (survey results) and here is what I found

• The question "Which Kubeflow components do you use (or will you use)?" had 147 responses
• Out of 147 responses, 92 responses contained either KFServing or KServe
• KFserving appeared in 49 responses
• KServe appeared in 71 responses
• There were 28 responses that selected both KFServing and KServe

(49 + 71 - 28) / 147 = 63% total responses for using either KFServing or KServe

With the assumption of 50 / 50 split in those 28 who chose both, we can also come up with ratios of KFServing and KServe

KFServing: (49 - (28 / 2)) / 147 = 24% KServe: (71 - (28 / 2)) / 147 = 39%

If we don't want to assume 50 / 50 split and show the ratios, maybe we just only show the combined percentage. WDYT

Thanks @jbottum and @annajung for the further analysis! I think the combined percentage (49 + 71 - 28) / 147 = 63% is reasonable, I can update with that number.
